Jealous?

Summary:

After surviving finals and earning their hero certifications, Classes 3-A and 3-B from U.A. High School throw one explosive senior party to celebrate. What starts as harmless chaos—drinking games, embarrassing dares, and nonstop laughter—slowly turns into something far more dangerous when Katsuki Bakugo and Izuku Midoriya begin circling each other with a tension no one in the room can ignore.

As Truth or Dare and spin the bottle spirals wildly out of control, buried feelings surface, jealousy ignites, and every glance between them feels like a countdown to disaster. With the entire class watching, one reckless night threatens to change everything.

Chapter 1: The party

Chapter Text

The whole week had been building to this exact moment, a slow-burning fuse of anticipation that had everyone on edge since Monday morning. But now that the final exams were officially behind them and the grueling hero certification results were locked in, the tension didn't collapse into exhaustion—it exploded into pure, unadulterated chaos. It's what they all have been hopping for. A little evening to finally relax and for once to let loose.

It was a remarkably warm evening, the kind where the twilight lingers just a bit longer than usual, casting long, amber shadows through the massive windows of the UA dorms. Breaking standard protocol and completely ignoring the usual inter-class rivalry, the entire headcount of Class 3-A and Class 3-B had crammed themselves into the 3A common rooms for a celebratory ringer.

The space, usually spacious enough for twenty teenagers, was bursting at the seams, transformed into a sprawling, loud, and messy party.

The bass from Mina's portable speaker setup was vibrating right through the floorboards, pumping a heavy beat that had half the room moving. The overhead lights had been dimmed, replaced by a chaotic grid of fairy lights and a stray strobe light that Kaminari was subtly powering with his own thumb to keep the rhythm going.

The air smelled like hot pizza, alcohol, and the unmistakable scent of body heat and a lot of different colognes. It was a bit overwhelming, yet also comforting.

Every square inch of the common area was claimed by a different brand of celebration. Right in the center of the room, Mina and Hagakure were leading a chaotic dance circle. They had somehow convinced Awase and Rin to join in, the latter looking incredibly out of his depth but trying his best anyway.

Sato and Manga had essentially taken over the kitchen island, constructing a massive pyramid of solo cups and deploying an endless supply of snacks. Sero was hovering nearby, using his tape to meticulously construct a makeshift trash chute from the counter straight to the bin to keep Iida from having a stress-induced meltdown.

In the corner by the couches, a brutally intense game of Mario Kart was underway. Jiro and Kamakiri were locked in a silent, dead-eyed stare-down, controllers gripped so tightly their knuckles were white, while a rowdy crowd of onlookers placed bets with leftover cafeteria coupons.

With the barrier between 3-A and 3-B completely melted away by the heat of the summer night, the interactions were pure gold.

Over by the punch bowl, Monoma was in peak form, dramatically holding a plastic cup aloft as he gave a theatrical, unsolicited speech about the philosophical superiority of Class B's quirk synergy. Instead of getting annoyed, Kirishima and Tetsutetsu were standing on either side of him, nodding solemnly and banging their fists against their chests in aggressive, emotional agreement.

"Man, your words... they're just so passionate!" Kirishima yelled over the music, wiping a fake tear from his eye.

"So manly, Monoma! So manly!" Tetsutetsu roared back.

Monoma blinked, utterly derailed by their genuine support, his smug smirk faltering into pure confusion.

Meanwhile, Bakugo was leaning against the far wall by the balcony doors, a scowl firmly fixed on his face and a glass of whatever whiskey he had poured gripped in his hand. He looked like he wanted to blast the entire room into orbit, but he hadn't actually left.

A few feet away, Todoroki sat calmly on a windowsill, sipping a whatever liquor box and watching the flashing strobe lights with an expression of profound, peaceful detachment.
Near the center of the chaos, Midoriya was laughing, his usual notebook nowhere to be seen for once in his life. He was surrounded by Uraraka, Asui, and Kendo, animatedly gesturing as he recounted a ridiculous story from the practical exam, his eyes bright and completely free of the week's stress.

They were seniors now. The future was coming for them fast, heavy with the weight of agencies, sidekick contracts, and the looming responsibilities of the pro hero world. But tonight? Tonight, they were just a bunch of teenagers throwing a violently loud party, celebrating the fact that they had survived it all together.

Before the sun had even completely dipped below the horizon, the atmosphere inside the 3-A dorms was already thick with a restless, frantic energy. It was that specific, golden hour of the late afternoon where the heat of the day was still trapped indoors, making the air feel heavy and alive. The party was only just kicking into gear, still possessing that slightly awkward, high-voltage friction of forty people trying to transition from exhausted students into functioning partygoers.

The transition from "polite gathering" to "complete lawlessness" happened the moment Kaminari accidentally overcharged the strobe light, causing a mini-EMP that temporarily blew the fuse to the main kitchen lights.

Instead of a lull, the sudden darkness elicited a collective, feral cheer from the crowd. When the backup generator clicked on a second later, the party had shifted gears.

Down on the floor, the Mario Kart tournament had devolved into high-stakes chaos. Kamakiri had just been struck by a blue shell inches from the finish line, prompting him to screech and accidentally slice a throw pillow cleanly in half with a blade extended from his forearm.

"Property damage! That's a five-point deduction from your hero license!" Jiro crowed, crossing the finish line in first place and throwing her hands up in victory while Kaminari, still acting as a human outlet, cheered so hard he short-circuited his own brain, his face blanking into his signature, mindless *wheee* expression.

Near the balcony, Bakugo watched the pillow feathers drift through the air like snow, his eye twitching. He took a slow, aggressive swig of his drink.

"Fucking extras," he muttered, though he notably didn't move an inch away from the warmth of the room.

"You know, Bakugo," Todoroki spoke up from his perch on the windowsill, his voice entirely level as he stabbed the straw into a second liquor box. "If you use your explosions at a micro-level, you could probably pop the popcorn kernels Sato left on the counter without burning the bag. It would be efficient."

Bakugo slowly turned his head, glared at Todoroki with the intensity of a thousand dying suns, and snarled, "I am a weapon of mass destruction, Half-and-Half, not a microwave."

"It's about precision control," Todoroki replied, entirely unbothered, taking a delicate sip.
Across the room, the crowd around Monoma had grown. Having failed to alienate Class 3-A with his usual superiority complex, he was now being forced to endure the ultimate nightmare:
aggressive, unconditional affection. Kirishima and Tetsutetsu had been joined by Shishida, who was gently but firmly patting Monoma on the back with a massive, fur-covered hand that threatened to dislocate the boy's shoulder with every beat.

"To think!" Monoma yelled, trying to regain his footing, his voice cracking slightly. "That we, the dark horses of Class B, must share a roof with you rowdy—"

"Bro, we share everything now! We're a brotherhood!" Kirishima wrapped an arm around Monoma's neck, pulling him into a suffocating side-hug. "Tell him, Shoda!"
Shoda, passing by with a plate of pigs-in-a-blanket, just smiled politely. "He's right, Neito. Just eat a hot dog."

Meanwhile, Midoriya was practically glowing, his laughter ringing out above the thumping bass of Mina's playlist. For the first time in three years, the constant, analytical ticking in his brain had shut off. He wasn't calculating trajectory, he wasn't worrying about the next villain threat, and he wasn't overthinking his quirk. He was just Deku, a nineteen-year-old kid who had passed his finals.
"And then," Midoriya was saying, tears of laughter pricking the corners of his eyes as he looked at Uraraka and Kendo, "Iida tried to use Recipro Burst to catch the falling test dummy, but he forgot the mud zone Pixie-Bob set up! He just... He looked like a very shiny, very fast mole."

"I did not look like a mole, Midoriya!" Iida's voice boomed from the kitchen island, where he was currently holding a trash bag open while Sero meticulously guided a crushed soda can down the tape-chute. "It was a tactical, low-profile recovery maneuver! And I expect proper sanitation standards to be upheld, even during a celebration!"

"Let it go, Class Rep!" Mina shouted, dancing her way past the kitchen and violently spinning Iida around by his shoulders. "Come on, give us a beat!"

The amber light outside finally faded into a deep, electric indigo, the stars bleeding into the sky above UA high. The future was waiting out there in the dark—daunting, unpredictable, and closer than it had ever been. But looking around the crowded, messy, vibrating room, at the mingled uniforms and the shared laughter of forty heroes-in-training, it was clear none of them were afraid.
They had built a fortress out of each other. And tonight, the fortress was throwing a hell of a party.

The bass from the speakers vibrated right through the floorboards, but Midoriya barely noticed the thumping music as he continued to sit on the edge of the crowded sofa, completely caught up in the energy of the party. He was in the middle of recounting a ridiculous training mishap with Ida again his hands gesturing wildly in the dim, colorful party lights.

Beside him, Uraraka was practically doubling over, clutching her stomach as she giggled, while Kendo leaned against the armrest, letting out a loud, breathless laugh and shaking her head at his sheer enthusiasm. Seeing his friends having such a good time was infectious, and Izuku just couldn't contain his laughter. It bubbled up from his chest—a bright, crinkle-eyed laugh that made his shoulders shake and brought a warm flush, entirely losing himself in the carefree spirit of the night.

But as he was laughing, his gaze instinctively drifted past the dancing crowds and the flashing strobe lights. That's when he caught eye contact with Katsuki.

Katsuki was standing across the room, leaning back against the wall away from the main cluster of people. He had a glass cup of whiskey held loosely in one hand, ignoring the loud chatter of the people around him. His sharp crimson eyes were fixed entirely on Izuku.

Even through the hazy, crowded room, the distance between them seemed to vanish. Katsuki looked somehow warm, a rare expression illuminated by the passing sweeps of colored light. It wasn't soft—his gaze was still as fiercely predatory as always, tracking Izuku's every movement with an intense, unyielding focus—yet something about the unwavering stare left Izuku with a sudden, suffocating lump in his throat.

The laughter died on his lips, melting into a faint, ragged exhale. The thumping bass and the voices of Uraraka and Kendo suddenly faded into background static as Izuku found himself completely pinned by that quiet, burning intensity from across the crowded room.

What the hell that was new.

It was a sudden, dizzying shift in gravity. One second Izuku was the epicenter of a loud, brightly colored circle of friends, and the next, he felt completely unmoored, anchored only by the heavy weight of crimson eyes.

Katsuki didn't look away. He didn't scoff, he didn't roll his eyes, and he didn't do that aggressive little head-jerk that usually meant *'What the fuck are you looking at?'* He just kept staring, his thumb slowly tracing the rim of his glass, his expression a strange, intoxicating quiet, uncharacteristic tolerance. Under that gaze, the ambient heat of the crowded dorm room suddenly felt tenfold hotter, localized entirely in the space right beneath Izuku's collarbone.

"Earth to Deku-kun?"
Uraraka's voice pierced through the static, her hand lightly tapping his shoulder. Izuku jumped, a violent, full-body flinch that nearly sent him toppling off the edge of the sofa.

"Y-yes! Right!" Izuku stammered, his voice pitching a full octave higher than normal as he scrambled to piece together his shredded train of thought. He frantically rubbed the back of his neck, his face instantly flushing a violent, sunburned crimson that had absolutely nothing to do with the party lights.
"I mean—sorry, what were we saying?"
Kendo raised an eyebrow, her sharp eyes darting to Izuku's burning face. "We were actually talking about the internships, Midoriya. But it looks like you got distracted"

"I'm not distracted! Just—air! It's really warm in here, right? Wow, Mina really cranked up the heating, or maybe it's just the beer, I handle beer patheticly—" Izuku babbled, his hands flying in a frantic blur of self-defense.

Across the room, as if sensing the disruption, Katsuki finally broke the stare. He brought the glass to his lips, taking a slow, deliberate sip while his eyes drifted toward the ceiling, a faint, almost imperceptible smirk tugging at the corner of his mouth. It was a victory lap in a silent game Izuku hadn't even realized they were playing.

"Manly tears, Monoma! That's what it is!"
The sudden, roaring outburst from Kirishima just a few feet away shattered the remaining tension. The red-haired hero had officially moved from hugging Monoma to forcefully hoisting him onto his shoulders like a trophy, while Tetsutetsu cheered them on by banging two empty soda cans against his own forehead. Monoma looked like he was trapped in a nightmare of pure solidarity, his arms flailing as he tried to maintain his aristocratic dignity while being paraded past the punch bowl.

"Put me down, you absolute Neanderthal!" Monoma shrieked, though his grip on Kirishima's shoulders was remarkably tight. "Class B does not require your primitive displays of physical lifting!"

"You're part of the family now, man! Let it out!"
Tetsutetsu bellowed back.

Izuku forced out a breathless laugh, desperately trying to anchor himself back into the chaotic reality of the room, but his chest still felt tight, his heart hammering against his ribs in a rhythm that completely ignored the bass from the speakers. For years, Katsuki's gaze had been a challenge, a threat, or a warning. But whatever that look was just now—heavy, lingering, and entirely unfiltered—it was a brand-new quirk altogether. And Izuku had absolutely no idea how to counter it.

The chaotic energy of the night refused to burn out, instead mutating into something looser and sweeter as the clock bled past midnight.
Sato's mountain of snacks had been entirely leveled, leaving a battlefield of empty solo cups and crumbs that Iida was still aggressively sweeping into Sero's tape-chutes. The heavy, thumping bass of Mina's playlist finally transitioned into a low, lo-fi groove that matched the exhausted, hazy vibe of forty teenagers who had given everything they had to their notebooks, their quirks, and their futures.
The dance floor had cleared out, leaving Mina and Hagakure collapsed giggling onto a pile of beanbags.

Down by the TV, the Mario Kart tournament had officially claimed its victims. Kamakiri was passed out cold on the floor, his face half-buried in the remains of the sliced throw pillow, while Jiro sat cross-legged on the couch, proudly wearing his headband like a trophy. Grinning like a menace.

It was Mina, of course, who sparked the final shift. Shaking off her exhaustion with a sudden, wicked burst of energy, she leaped onto the coffee table, clapping her hands together.

"Alright, listen up!" she yelled, her voice cutting through the ambient chatter. "The dancing is dead, the pizza is gone, and half of you are looking way too peaceful. I refuse to let this night end without some proper, high-stakes psychological warfare!"

"Ashido, please get off the furniture! It's a safety hazard!" Iida protested, his arm chopping the air with rhythmic, automatic discipline.

"Hush, Class Rep! It's time for the ultimate senior tradition," Mina grinned, her eyes scanning the crowded room. "We are playing Truth or Dare!"

A collective groan mixed with a few eager cheers rippled through the combined classes.
"Oh, brilliant," Monoma muttered from his seat on the floor, finally free of Kirishima's suffocating hugs but still looking thoroughly rumpled. "A game designed entirely for Class A's blatant exhibitionism."

"Don't chicken out now, Monoma!" Tetsutetsu roared, slapping him on the back again. "It's a test of courage!"

Within minutes, the sprawling chaos of the room condensed into a massive, tightly packed circle right in the center of the common area. Sofas were dragged backward, beanbags were thrown into a perimeter, and forty heroes-in-training crammed themselves shoulder-to-shoulder on the floor.

The transition brought a sudden, heavy hush over the room. The strobe lights were turned off, leaving only the warm, amber glow of the fairy lights casting long shadows across the circle. It felt intimate—almost dangerously so—after hours of loud music and screaming.

Izuku sat wedged between Uraraka and Todoroki, his knees pulled up to his chest. He was doing an exceptionally poor job of looking relaxed. His eyes kept darting across the circle, because as fate—or the cruel physics of the room—would have it, Katsuki had taken a seat directly opposite him.

Katsuki was sitting with his legs stretched out, his back resting against the base of an armchair. He had traded his empty whiskey glass for a stray can of beer, holding it loosely between his knees. He wasn't yelling. He wasn't threatening anyone. He was just watching, his crimson eyes gleaming in the dim light, heavy and unreadable.

When Izuku accidentally met his gaze again, Katsuki didn't look away. Instead, he tilted his head just a fraction of an inch, a slow, deliberate challenge cutting through the quiet of the room. Izuku's didn't understand what had shifted, his fingers tightening against the fabric of his jeans.

"Alright, the rules are simple," Mina announced, spinning an empty green bottle in the dead center of the floor. "You can't choose 'Truth' three times in a row, and Quirk usage is allowed *only* if the dare demands it. No backing out."

The bottle whirled across the hardwood, its plastic scratching against the floorboards as forty pairs of eyes tracked its motion. The room was completely silent now, save for the hum of the backup generator and the distant chirp of summer cicadas outside.

The bottle slowed down, its cap stuttering past Asui, past Kaminari, before finally clicking to a dead stop.
It was pointing directly at Kirishima.
"Yes! Hit me!" Kirishima grinned, cracking his knuckles. "Give me a dare, Ashido! Make it manly!"

Mina's face contorted into a deeply unsettling, mischievous smirk. "Oh, Kirishima. You should never have given me that kind of power."

As Mina leaned forward to whisper the dare, the circle leaned in with her, the quiet tension in the room stretching tight. Izuku tried to focus on Kirishima's impending doom, but he could still feel the phantom heat of Katsuki's stare burning right through the dark, waiting for something.

Mina leaned forward, her eyes flashing with pure malice as she rested her chin on her hands. "Kirishima, my manly friend... your dare is to sit perfectly still and let someone tickle you for one full minute. No hardening allowed!"

"What?! No way!" Kirishima's jaw dropped, his tough guy facade instantly crumbling into sheer panic. "Ashido, come on! Anything but that! Punch me in the face! Make me do five hundred push-ups!"

"Nope! Rules are rules!" Mina cheered, already scanning the circle for a willing executioner. "And since he's sitting right there... Sero! Get him!"
Sero grinned like a goblin, cracking his knuckles as he slithered forward. Kirishima looked like a man facing a firing squad. He squeezed his eyes shut, forcing his hands flat on the floor to keep himself from activating his quirk.

The moment Sero's fingers dug into Kirishima's ribs, the red-haired powerhouse completely lost it.
"PFFFT—HAHAHA! NO! WAIT! SERO, STOP—!" Kirishima shrieked, his face turning as bright red as his hair. He writhed wildly on the floor, his legs kicking out as he tried desperately not to harden his skin. It turned out the manliest guy in Class 3-A was also catastrophicly ticklish.

"Thirty seconds!" Kaminari cackled, checking his phone timer while Tetsutetsu watched in absolute, horrified fascination.

"Stay strong, brother!" Tetsutetsu cheered, holding his own ribs in sympathy. "Endure the agony!"

"I CAN'T! HE'S GOT PROPELLER FINGERS!" Kirishima howled, tears streaming down his face as Sero relentlessly targeted his armpits and sides. By the time Kaminari shouted "Time!", Kirishima collapsed onto his back, wheezing, panting, and thoroughly defeated.
"You guys... are monsters," he gasped, wiping his eyes.

Once he caught his breath, Kirishima dragged himself up and grabbed the green glass bottle. "Alright, my turn for revenge," he muttered, giving the bottle a vicious spin.

The plastic cylinder blurred across the floor, slowing down until the cap pointed squarely at the straightest posture in the room: Tenya Iida.

"Ah! Me?!" Iida gasped, his glasses reflecting the fairy lights as he immediately went rigid.
"Truth or dare, Class Rep?" the room chanted in unison.

Iida cleared his throat, adjusting his glasses with a sharp, robotic chop of his hand. "As a student representative and a future pro hero, I must always face challenges head-on! I choose... Truth!"

"Booo!" Mina, Kaminari, and Sero immediately chorused.

"Don't be a coward, Iida!" Kendo called out from across the circle, a playful smirk on her face. "Class A's representative can't handle a dare?"

The peer pressure from forty teenagers was a physical force. Iida's face flushed under the scrutiny. He puffed out his chest, his disciplinary resolve cracking under the weight of his peers' expectations. "Very well! If it is a matter of Class UA's pride, I alter my choice! I choose Dare!"

The circle erupted into cheers. Kirishima rubbed his hands together, a wicked idea forming. "Alright, Iida. Open up your phone. You have to send a weird, completely contextless GIF to the tenth person on your contact list."

Iida blinked, pulling out his sleek, pristine smartphone. "A... 'weird GIF'? That seems highly unprofessional, but... very well let me look who the contact is." He unlocked his phone, sliding his finger down his carefully alphabetized contact list. 1, 2, 3...

Suddenly, Iida's entire face drained of color. He went so stiff he looked like a marble statue.
"Who is it, Iida?" Uraraka leaned over, trying to peek.

"It... It is Aizawa-sensei," Iida whispered, his voice trembling with a level of fear usually reserved for All For One. A collective, thrilled gasp sucked the air out of the room.

"Oh, you have to do it now," Jiro laughed, leaning forward. "No backing out!"

"This is a violation of student-teacher boundaries!" Iida panicked, his fingers hovering frantically over the screen. But Sero and Mina were already flanking him, scrolling through his GIF keyboard. Mina aggressively tapped on a flashing, hyper-saturated GIF of a spinning, cross-eyed cat dancing on a rainbow under the text: *'YIPPEE! IT'S WIGGLE TIME!'*

"Send it," Mina whispered like a demon on his shoulder. With a shaking thumb, pressed on by Sero's guiding hand, Iida hit send.

The circle fell into a dead, suffocating silence. Nobody breathed. Forty teenagers stared at Iida's phone, waiting for the inevitable wrath of Shota Aizawa at 12:30 AM.

For two agonizing minutes, nothing happened. Then, the phone buzzed.
Iida practically jumped out of his skin. With trembling hands, he held the phone up so the group could see the screen.

Aizawa had replied. "If this is your way of telling me the dorms are on fire, put it out yourself. If this is a prank, you have extra morning couch-moving duty tomorrow. Go to sleep."

The room exploded into stifled, silent screams of laughter, people slamming their hands against the floor to keep from waking up the faculty dorms. Even Todoroki let out a soft, amused huff from his windowsill.

The structural integrity of Iida's dignity had thoroughly collapsed, but the game marched on. While the Class Rep was busy in the corner, aggressively typing a three-paragraph apology to Aizawa-sensei detailing the sociological pressures of peer-influenced recreational activities, a thoroughly recovered Kirishima clapped his hands.
"Alright, Iida's compromised! Someone spin the bottle!"

Pony Tsunotori lunged forward from her patch of carpet, her hooves clicking against the floorboards as she gave the green bottle a sharp twist. The plastic spun, catching the low, amber glow of the fairy lights before slowing down and targeting the back corner of the circle. The tip pointed directly at Shihai Kuroiro.

The resident "Scheming Hero: Vantablack" didn't flinch. He merely let out a low, theatrical chuckle that sounded like it had been imported directly from a gothic horror film.

"The wheel of fate turns to the darkness," Kuroiro muttered, his dark eyes gleaming out from his ink-black skin. "I choose Truth. Shadows have no secrets."

"Oh, no you don't!" Mina called out, pointing a finger at him. "You spent half of last year lurking in the Class A kitchen cabinets trying to scare Tokoyami. We want to know: what is the most embarrassing thing you witnessed while hiding in the shadows?"

Tokoyami looked up sharply, his arms crossed over his chest as Dark Shadow poked its head out from his cloak, looking equally intrigued.

Kuroiro paused. For a second, his perpetually smug expression faltered, a deep lavender blush struggling to show through his pitch-black complexion. He cleared his throat, pulling his collar up slightly. "I... may have slipped into the Class 3-B common room ceiling vents during the winter term to map out a strategic tactical ambush."

"Get to the point, Kuroiro!" Kaibara called out, throwing a stray popcorn kernel at him.

"I witnessed Monoma practicing his 'triumphant villainous laugh' in front of a full-length mirror," Kuroiro admitted, his voice dropping an octave. "He was wearing a cape made of a bath towel. He did it for forty-five minutes. He... he choreographed a spin."

The circle instantly turned to Monoma. The phantom of his aristocratic dignity shattered in real-time.

"It was character work!" Monoma shrieked, his voice cracking spectacularly as his face flushed a violent crimson. "A hero must master the art of psychological intimidation! Sen Kaibara, do not look at me like I am a circus oddity! It was a calculated theatrical exercise!"

"Forty-five minutes, man?" Kaminari wheezed, clutching his stomach. "That's dedication."

To save his classmate from total psychological annihilation, Itsuka Kendo grabbed the bottle, giving it an aggressive spin. "Moving on before Neito pops a blood vessel!"

The bottle zipped across the floor, its frantic rattling drawing everyone's eyes back to the center. It stuttered, clipped Koda's shoe, and finally slid to a halt. The cap was pointed directly at Jurota Shishida.

The massive, beast-like student blinked, his large glasses sliding slightly down his snout. "Ah. It appears I have been selected. In the spirit of the evening's boisterous atmosphere, I shall choose Dare."

"Oh, I've got a great one for the big guy," Setsuna Tokage laughed, her sharp teeth flashing in the dim light. "Shishida, you have to let Yanagi use her quirk on you, and you have to act out a scene from a tragic romance novel as a floating ghost."

Reiko Yanagi didn't say a word. She just smiled her signature, ghostly smile, her hands rising into a classic, limp-wristed spirit posture. Her eyes glowed with a faint, eerie light as her quirk, Poltergeist, activated.

Suddenly, Shishida's massive, muscular frame—even without his beast form activated—was lifted three feet off the ground. He floated horizontally in mid-air, looking entirely out of place among the delicate fairy lights.

"Oh, cruel fate!" Shishida suddenly boomed, instantly committing to the bit. He threw a large hand over his brow, drifting lazily through the air like a hairy, heavy cloud. "Why must we be separated by the mortal coil? I am but a specter of love, destined to haunt the snack table for eternity!"

"Bravo! Emotional!" Tsunotori cheered, clapping her hands.

"He's actually got great core control for a ghost," Sato observed, thoroughly impressed by the sheer physics of a hundred-plus kilogram teenager hovering over the coffee table.
Yanagi gently lowered Shishida back to the carpet, where he adjusted his glasses and offered a polite, Victorian bow. "Thank you. A most exhilarating aerial experience."

While the laughter from Shishida's theatrical flight was still bubbling through the room, the massive student reached out and spun the bottle. It didn't take long to slow down. It skated past Uraraka, knocked into Todoroki's liquor box, and clicked to a definitive stop.

The room went entirely, utterly quiet.
The cap was pointing straight at Katsuki Bakugo.

The collective air in the room seemed to vanish. A few Class B students looked toward the exit, suddenly remembering that Bakugo's temper had a body count. Beside Izuku, Uraraka held her breath.
Katsuki didn't move. He was still leaning against the base of the armchair, his legs stretched out carelessly. His beer can was held loosely in his palm, the aluminum crinkling slightly under the subconscious pressure of his grip. Slowly, his crimson eyes flicked up from the bottle, bypassing the rest of the room entirely, and locked right onto Izuku.

The silence stretched, heavy and suffocating.
"Well, Bakugo?" Mina asked, her usual booming confidence dropping into a slightly cautious, testing tone. "Truth or dare?"

Katsuki took a slow, deliberate sip of his beer, his eyes never leaving Izuku's face. The heat beneath Izuku's collarbone flared up again, hot enough to scorch.

"Dare," Katsuki growled, his voice a low, gravelly rasp that cut right through the quiet room. "Make it quick, raccoon eyes."

Mina's eyes widened to the size of dinner plates. For a fraction of a second, even the fearless pink queen of Class 3-A looked like she realized she was playing with high-grade explosives. But the sheer, unadulterated chaos of a late-night senior party—and the lingering adrenaline of watching Iida text a dancing cat to Aizawa—overrode her survival instincts.

A slow, deeply wicked grin spread across her face.
"A dare. Bold choice, Bakugo," Mina purred, leaning so far forward over the coffee table she was practically horizontal. She glanced toward the kitchen island, where Sato still had a stray, aerosol can of whipped cream sitting out from the dessert prep. Her eyes flicked back to Katsuki, then darted, with sniper-like precision, across the circle.

"Sato! Toss me the whipped cream!" she called out.
The can sailed through the air, and Mina caught it with a practiced flourish. She set it dead center in the circle, right next to the empty green bottle.

"Here's your dare, Dynamight," Mina announced, her voice echoing in the sudden, breathless hush of the room. "You have to spin this bottle one more time. Whoever it lands on... you have to use that whipped cream to draw your own hero agency emblem, or your initials, on a patch of their bare skin—like an stomach, but here is the kicker: you can only use your tongue to do it. No hands. No napkins."

A collective, high-pitched gasp hissed through the room.
"Ashido! That is highly inappropriate for a school-sanctioned residential environment!" Iida's voice cracked from the corner, his arm frantically chopping the air despite his thoroughly crushed authority.

"Oh, shut up, Iida, he's nineteen!" Setsuna Tokage cackled, rubbing her hands together in absolute glee. "This is premium drama!"

Katsuki didn't blink. His expression didn't shatter into explosions, and he didn't roar a threat. Instead, his jaw set into a hard, rigid line, the aluminum of his beer can groaning loudly as his grip tightened, flattening the metal. His crimson eyes darkened, fixed on the glass bottle in front of him.

"Fucking ridiculous," Katsuki growled, his voice dangerously low.

"Are you backing out, Bakugo?" Monoma taunted from a safe distance behind Shishida's massive shoulder, sensing a rare moment of vulnerability. "Is the great Class A powerhouse intimidated by a simple—"

"Shut the fuck up, Copycat," Katsuki snapped.
Slowly, deliberately, Katsuki leaned forward. The entire room leaned with him, forty teenagers holding their breath so tightly the silence was deafening. He reached out a broad, calloused hand, his fingers brushing the cold glass of the green bottle. With a sharp, aggressive flick of his wrist, he sent it spinning.

The bottle blurred.
The sound of the glass scratching against the hardwood floorboards sounded like a countdown. Izuku couldn't breathe. He kept his knees pulled tightly to his chest, his eyes glued to the green cylinder as it spun past Kaminari, past Todoroki—who was watching with wide, entirely blank interest—past Jiro, slowing down... slowing...
It stuttered. It clipped the edge of a floor mat.
And with a final, agonizing *click*, the cap pointed straight ahead.

Directly between Izuku's sneakers.

The silence that followed was absolute. You could have heard a pin drop on the UA campus. Mina let out a muffled, strangled squeak of pure, unscripted shock. Beside Izuku, Uraraka's jaw dropped, her eyes darting between Izuku and Katsuki as if expecting the room to spontaneously combust.
Izuku froze, completely paralyzed, his green eyes blown wide.

Of course. Of course, the universe, with its twisted sense of humor, would do this.
Across the circle, Katsuki looked at the bottle, then slowly raised his eyes to meet Izuku's.
There was no explosion. No shouting. But the look in Katsuki's crimson eyes was so intensely focused, so heavy with a sudden, suffocating gravity, that Izuku felt a shiver race straight down his spine. The ambient heat of the room vanished, replaced by a hyper-localized fire burning right beneath his collarbone. Oh hell no Izuku thought. Of course him.

Katsuki stood up.
He didn't hesitate. He tossed the crushed beer can behind him into Sero's tape-chute without looking, walked into the center of the circle, and picked up the can of whipped cream.

Every eye in the room followed his movements like he was a predator stalking across the savannah.
He stopped right in front of Izuku, towering over him in the dim, golden glow of the fairy lights.
"Deku," Katsuki rasped, his voice cutting through the static in Izuku's ears. "Pull your shirt down."

The room seemed to drop ten degrees, yet Izuku felt like he was being baked alive from the inside out. Forty pairs of eyes locked onto them, the silence so dense it felt physical.

"K-kachan" Izuku stammered, his voice betraying a desperate, high-pitched tremor as he looked up from his curled position on the floor. "Come on, it's just a game, we don't actually have to—"

"I don't back down from a dare, dumbass" Katsuki interrupted, his voice dropping into a low, gravelly register that made the hairs on the back of Izuku's neck stand up. He shook the aerosol can, the rhythmic, metallic clinking of the mixing ball inside sounding like a death knell. "Get on your back."

Izuku's throat dry-swallowed. His entire body felt heavy, his muscles locking up in a mix of panic and a strange, intoxicating vertigo. Slowly, under the unyielding weight of Katsuki's crimson gaze, he uncurled his legs and leaned back against the cushions of the sofa behind him, sliding down until he was lying flat on the carpet. Well this is it, he has officially reached a new point of degradation.

With shaking fingers, Izuku reached down to the hem of his dark t-shirt. He pulled it up, bunching the fabric over his chest to expose the pale, hard-earned expanse of his stomach. His abs were tightly wound, his chest rising and falling in shallow, frantic breaths that he couldn't control.
A collective, muffled gasp rippled through the circle. Mina looked like she was losing her mind, her hands clamped tightly over her mouth to keep from screaming, while Kirishima stared with wide, completely stunned eyes, suddenly realizing the sheer scale of the chaos they had unleashed.

 

Katsuki dropped to his knees, straddling Izuku's hips. The sudden, solid weight of him pinned Izuku to the floor, cutting off any lingering thought of escape.

Without a word, Katsuki inverted the can. He pressed the nozzle. A sharp hiss cut through the quiet room as a thick, white dollop of whipped cream bloomed directly over Izuku's navel, followed by a slow, deliberate line that traced up the center of his abdomen, ending right between his pectoral muscles. The cold sweetness of the cream contrasted sharply against Izuku's burning, overheated skin, causing him to arch slightly with a sharp, involuntary intake of breath.

Katsuki tossed the can aside. It rolled away, ignored, as he leaned down.
The distance between them vanished. Izuku could smell the faint, sharp scent of the whiskey Katsuki had been drinking, mixed with the sweet, vanilla aroma of the cream and the underlying, ozone-like heat of Katsuki's own skin. Izuku felt his mind go numb.

Katsuki's hands planted firmly on the floor on either side of Izuku's shoulders, caging him in. He dipped his head, his sharp jawline cutting through the dim, golden shadow cast by the fairy lights.
Then, his tongue met Izuku's bare skin.

Izuku's eyes blew wide, his fingers violently twitching into the carpet. Katsuki started at the base of his stomach, his tongue hot, broad, and terrifyingly deliberate as he dragged it upward, wiping away the cold cream in a single, sweeping motion. The contrast of Katsuki's hot, wet tongue against the chilled sweetness sent a violent jolt of electricity straight down Izuku's spine.

A quiet, breathless gasp escaped his lips, his abdominal muscles flexing hard under the pressure. Nobody but himself could hear it.

Katsuki didn't rush. His tongue traced the contours of Izuku's abs, licking away the white cream with a fierce focus. He moved higher, crossing over Izuku's ribs to his chest. Izuku's heart was hammering so violently against his ribs he was certain Katsuki could feel it against his jaw. Izuku felt everything had disappeared yet he could feel 40 eyes on him, burning him harder then anything before.

As Katsuki licked the final swirl of cream from the center of Izuku's chest, his tongue dragged slowly over the warm, bare skin, leaving a slick, tingling trail in its wake.

For a fraction of a second, Katsuki paused. His face was inches from Izuku's neck, his hot breath fanning across Izuku's collarbone. His crimson eyes flicked up, meeting Izuku's blown-out, dazed green gaze from a breath away. There was a raw, unfiltered heat in Katsuki's expression—something dark and heavy that went far beyond the rules of a party game. He had never seen him like this.

Slowly, Katsuki pulled back, sitting up on his knees. He swiped his thumb across the corner of his lower lip, catching a stray trace of cream, and swallowed it, his eyes never leaving Izuku's flushed, burning face.

The room remained absolutely, agonizingly silent. Nobody moved. Nobody breathed. The sheer, suffocating gravity of what had just happened left forty loud, chaotic teenagers completely paralyzed.

The silence stretched so thin it felt like it would snap under the weight of forty racing heartbeats. No one laughed. No one teased. Even Monoma looked thoroughly stunned, his mouth slightly open as he stared at the center of the room.
Katsuki slowly stood up, shifting his weight off Izuku's hips. The loss of his sudden, heavy warmth left Izuku feeling completely exposed, his skin tingling where the cool air of the common room hit the damp, heated tracks Katsuki's tongue had left behind.

Izuku lay there for a second longer, his mind a chaotic, short-circuited mess of static. His t-shirt was still bunched up in his trembling fists, exposing his chest, which was heaving with uneven, shallow breaths. His face was a uniform, blinding shade of crimson that extended all the way down his neck and into the collar of his shirt.
Realizing forty people were watching him disintegrate in real-time, Izuku abruptly scrambled backward, his heels digging into the carpet as he yanked his shirt down over his stomach. He threw himself back onto the sofa cushions, burying his gaze into the ground, burning silent holes. His ears felt like they were on fire.

"Oh my god," Mina finally whispered, breaking the spell. Her voice was a mix of terror and absolute, unhinged awe. She looked at Katsuki, who had walked back to his armchair and sat down as if he hadn't just altered the gravity of the entire room.
Katsuki picked up a fresh can of beer from the floor, cracked the tab with a sharp *snap*, and took a slow drink. His chest rose and fell slightly faster than usual, and a faint, dark flush crept up his neck, but his crimson eyes remained fixed on the floorboards, refusing to give anyone the satisfaction of a reaction.

 

"Bro..." Kirishima managed, his jaw still slack as he looked between the two of them. "That was... you really didn't back down. That's... commitment to the game."

 

"Shut up, Shitty Hair," Katsuki growled into his beer, though the usual explosive venom was missing, replaced by a low, warning rumble.
"R-Right! Moving on!" Kaminari squeaked, his voice cracking spectacularly as he desperately tried to save the collective sanity of the room. He lunged forward and grabbed the green tea bottle, his hands shaking slightly. "The game must go on! Let's just... spin it again!"

 

He gave the bottle a frantic twist. It whipped across the floor, but nobody was really watching it anymore. The atmosphere in the circle had completely shifted from lighthearted high-school drama to something thick, heavy, and charged with an unspoken tension that everyone was suddenly too terrified to poke at.

Beside Izuku, Uraraka gently placed a hand on his shoulder. "Deku-kun? Are you... do you need something to drink?"

 

Izuku just let out a weak, muffled groan into his palms, his shoulders shaking. He could still feel the exact phantom sensation of Katsuki's hot, damp tongue dragging over his skin, tracing the line of his ribs, the deliberate, unhurried pressure of it. It felt branded into his skin.

Across the circle, Katsuki finally lowered his beer can. His eyes flicked upward, cutting through the dim amber light of the room, and locked right onto the gaps between Izuku's fingers. He didn't smirk. He didn't look triumphant. He just watched Izuku hide himself away, his expression dark, unreadable, and intensely patient.

The green bottle blurred across the hardwood floor, a spinning plastic blade trying—and failing—to slice through the dense, heavy fog that had settled over the room.

Kaminari's frantic spin finally slowed, the base rattling a rhythmic beat until it pointed directly at Itsuka Kendo.

A small, collective sigh of relief rippled through Class 3-B. Kendo was sensible. Kendo was grounded. She was the anchor that would pull this party out of the dangerously high-voltage territory Katsuki and Izuku had just dragged it into.

"Truth," Kendo said immediately, not even waiting for the prompt. She crossed her arms, offering a steady, no-nonsense smile. "I am not risking whatever chaotic energy is floating around the center of this carpet right now."

"Aw, living up to the 'Big Sister' reputation, Kendo?" Setsuna Tokage teased, her eyes gleaming as she leaned forward on her elbows. "Fine. If you want a Truth, you get a real one. We've all seen how you handle Class B, especially Monoma. But everyone here wants to know: who is the one person in this entire room—Class A or B—that you actually find the most intimidating, and why?"

A murmur of interest rippled through the circle. Kendo was a powerhouse, both physically and mentally. Seeing her truly shaken was a rarity.
Kendo blinked, her sharp eyes scanning the faces around the circle. They lingered briefly on Bakugo, passed over Todoroki, and finally came to a stop right on Izuku who was still trying to evaporate into the sofa cushions.

"Honestly?" Kendo said, her voice turning uncharacteristically quiet. "Midoriya."
Izuku's head snapped up, his green eyes wide and blinking through his messy curls. "Me?"

"Yes, you," Kendo nodded, a small, entirely serious smile touching her lips. "During the joint training and the exams, watching you switch from this incredibly polite, stuttering boy into someone who can analyze an entire battlefield in three seconds... it's terrifying, Midoriya. When your eyes change and you get that look like you've already figured out ten different ways to break through our defenses, it makes the back of my neck go cold. It's an incredible kind of intimidation."

"Wow, that’s honest." Kuroiro muttered from the shadows.
Izuku felt a different kind of heat hit his cheeks—this time, a profound, humbling wave of embarrassment. "Thank you, Kendo. I don't mean to be scary, I just—the tactical data is just very fascinating and—"

"Don't ruin the compliment, Deku," Katsuki's gravelly voice cut through his rambling. He hadn't looked up from his beer, but the line of his shoulders had tightened slightly at Kendo's words.
Kendo laughed, reaching out to give the bottle a sharp, deliberate twist.

"My turn to stir the pot." The plastic cylinder whipped around, its momentum dying down until the cap slid to a definitive halt, targeting Todoroki Shouto who was currently trying to extract the very last drop of juice from his liquor box with a loud, hollow sucking sound.

"Ah," Todoroki said, lowering the box. "Me."

"Truth or dare, Todoroki?" Kendo asked.
Todoroki looked at the empty box, then at the empty space where the snacks used to be. "Dare. The truths involve too much talking."
A ripple of excitement zipped through the room. Todoroki doing a dare was a rare, unpredictable wildcard.

Mina, instantly recovering her status as the resident demon of operations, leaned across the carpet. "Oh, I've been waiting three years for this! Todoroki, your dare is to walk over to the person you think has the most attractive features in this room, sit directly in front of them, and use your right side to warm up their hands while staring into their eyes for thirty seconds. No blinking allowed."

The circle let out a low, collective 'Ooooooh' that was distinctly more scandalous than the previous rounds. The game wasn't just returning to its chaotic baseline; it was evolving into something far more intense, fueled by the late hour and the lingering heat of the summer night.
Todoroki didn't look flustered. He didn't even pause to think. He simply slid off the windowsill, his movements fluid and unhurried. The entire room held its breath, forty pairs of eyes tracking him as he stepped over Sero's legs, bypassed Kirishima, and walked straight toward the sofa area.

He stopped directly in front of Momo.
Momo's breath caught, a beautiful, stark pink instantly blooming across her cheeks as Todoroki dropped onto his knees right in front of her. The proximity was staggering; their knees were practically touching on the carpet.

Without a word, Todoroki reached out, gently taking both of Momo's hands in his right hand. A soft, ambient warmth began to radiate from his skin, a gentle, soothing heat that immediately countered the chilly draft of the air conditioner.
"Thirty seconds starts... now!" Mina whispered loudly, checking her phone.

Todoroki leaned in slightly, his mismatched grey and turquoise eyes locking onto Momo's dark ones. His expression was completely serious, devoid of any playful teasing, which only made the intensity of the gaze tenfold heavier. Momo's chest rose and fell in a rapid rhythm, her fingers involuntarily twitching against his warm palm. She tried to maintain the stare, but the sheer, unfiltered focus of Todoroki's undivided attention had her biting the inside of her cheek, her heart visibly hammering against her collarbone.

"Ten seconds..." Kaminari counted down, leaning forward so hard he almost tumbled into the center.
Todoroki didn't blink. A stray wisp of steam drifted from his right shoulder, the physical manifestation of his quirk responding to the subtle spike in his own pulse.

When Mina finally yelled "Time!", Momo let out a breathless laugh, gently pulling her hands back and fanning her face, which was now thoroughly flushed.

"Your precision control is... very impressive, Todoroki." she managed, her voice a little higher than usual.

"Your hands were cold," Todoroki replied simply, sitting back on his heels, entirely unaware—or perhaps entirely aware—of the romantic devastation he had just left in his wake. He reached out and spun the bottle with a flick of his wrist.
The bottle didn't go far. It spun rapidly before snapping its cap directly toward Neito Monoma.

"Ha!" Monoma scoffed, though he slid back a few inches against the armchair. "The golden boy attempts to ensnare me in his web of theatrical traps. I choose Truth! A mind as brilliant as mine has nothing to hide from the crass curiosity of Class A."

Todoroki tilted his head. "Monoma. During the culture festival and the school plays, you spent a lot of time writing scripts. Who is the person from Class A that you secretly think would make the best romantic lead, and why haven't you asked them to be in one of your productions?"

A stunned silence dropped over the room.
"Oh, damn, Todoroki went for the throat," Jiro laughed, leaning back against the couch.
Monoma's smug expression froze. His eyes darted around the circle, his aristocratic posture stiffening until he looked like a statue. "I—romantic lead? From Class A? Preposterous! Your class possesses the dramatic subtlety of a collapsing building! To suggest that I, Neito Monoma, would look at any of you and see artistic value—"

"Answer the question, Monoma," Tetsutetsu roared, nudging him aggressively. "It's a matter of artistic integrity!"

Monoma swallowed, his face turning a chaotic shade of pink that clutched at his throat. His eyes flicked briefly, almost imperceptibly, toward Jiro, before darting away to the ceiling. "Jiro Kyoka," he muttered, his voice dropping its usual theatrical volume entirely. "Her... her musical aptitude carries a certain melancholic resonance that would suit a tragic, high-stakes narrative. But I would never ask because her classmate—" he glared violently at Kaminari "—would undoubtedly ruin the rehearsal space with his idiot electricity!"

"Hey! I can be dramatic!" Kaminari protested, though the rest of the room was already cheering and howling at Monoma's genuine words.

Desperate to redirect the spotlight, Monoma lunged forward and launched the green bottle into a ferocious spin. "Let the wheel of judgment strike down someone else!"

The plastic cylinder screamed against the floorboards, spinning with so much force it looked like a blur. The tension in the room, already amplified by Todoroki and Momo's intense stare-down, tightened like a guitar string.
The bottle began to slow. It drifted past Hagakure. It skated past Sato.
And then, with a heavy, final thud, the cap lined up perfectly. It was pointing right back once again at Katsuki Bakugo.

The laughter died instantly. The temperature in the room didn't just drop; it felt like the air pressure plummeted.

Katsuki slowly lowered his beer can. The faint flush that had been lingering on his neck from the whipped cream incident hadn't fully faded, and now, it burned into something sharper, darker.

He looked at the bottle, then slowly raised his eyes.
He didn't look at Monoma. His crimson eyes sliced straight across the radius of the circle, bypassing everyone else, and locked right back onto Izuku. He wanted to scream.

"Dare," Katsuki growled, his voice a low, vibrating rumble that shook the floorboards more effectively than Mina's bass ever could. He leaned forward, resting his elbows on his knees, his hands loosely clasped in front of him. The unyielding, heavy weight of his gaze pinned Izuku to the couch before a single word was even spoken. "And since the Copycat spun it, he gets to name it. Make it dirty, Monoma. I fucking dare you."

Monoma's breath hitched. He had wanted a moment of triumph over Class A's king, but looking into the raw, territorial fire currently burning in Katsuki's crimson eyes, he realized he wasn't holding a victory card—he was holding the pin to a grenade.

Monoma swallowed hard, his eyes darting from Katsuki's fierce, predatory posture to Izuku, who was already scraming, his hands gripping the fabric of his jeans so tightly his knuckles were white.

The entire room hung in the balance, the quiet so absolute that the distant summer cicadas outside sounded like a roaring chorus, waiting for the spark to hit the fuel.

Monoma's aristocratic confidence evaporated in real-time under the blistering heat of Katsuki's glare. He looked around the circle for backup, but even Tetsutetsu was holding his breath, recognizing the shift from a harmless party game to something dangerously real.

Monoma swallowed hard, his mind racing to find a dare that would maintain his pride without resulting in the literal combustion of the 3-A common room. His eyes flicked to the green bottle, then to the lingering, faint trace of dampness on Izuku's shirt where the whipped cream had been just twenty minutes prior. A wicked, desperate flash of inspiration hit him.

"You want a dare, Bakugo?" Monoma purred, his voice pitching higher to mask a tremor. "Fine. Class B challenges your absolute control. Since you claim to fear nothing, your dare is to spin that bottle one more time. Whoever it lands on, you have to crawl across the circle, pin them, and whisper the most scandalous, unfiltered thought you've had about them, directly into their ear. No filters. No backing out."

A collective, high-pitched gasp hissed through the room. Mina looked like she was about to pass out from sheer, unadulterated joy.

"Monoma, that is an egregious violation of personal boundaries!" Iida roared, his glasses practically steaming up as he tried to stand. Sero and Sato immediately grabbed his shoulders, pulling him back down. "Sit down, Class Rep! We are witnessing history!" Sero whispered fiercely.

Katsuki didn't blink. His jaw set so hard a muscle twitched in his cheek. He didn't yell, didn't threaten to blast Monoma into orbit. Instead, his crimson eyes darkened into a shade of raw red.

"Fucking easy," Katsuki growled, his voice a low, gravelly rasp that sent a visible shiver down the spines of the students sitting closest to him.
He leaned forward, his broad chest cutting through the warm, amber light of the fairy lights. His calloused fingers gripped the neck of the green bottle. With a sharp, violent snap of his wrist, he sent it into a ferocious spin.

The glass screamed against the hardwood.
Forty pairs of eyes tracked the green blur. Izuku felt his heart hammering against his ribs like a trapped bird. The ambient heat of the room vanished, replaced by a hyper-localized fire burning right beneath his collarbone. He could sense it, god's cruel plan. Please, anyone else, Izuku prayed silently, his knuckles white as he gripped his jeans. Kaminari. Todoroki. Anyone.

The bottle began to slow. It drifted past Asui. It skated past Todoroki, who watched with wide, unblinking interest. It stuttered on a groove in the floorboards, its momentum dying down... down...
And with a final, definitive click, the cap lined up perfectly.

Directly between Izuku's sneakers.
For the second time that night, the universe delivered a statistical impossibility. The silence that followed was so heavy it felt structural. Mina let out a muffled, strangled squeak into her hands. Beside Izuku, Uraraka slowly raised her hands to her face, her eyes wide with shock. She looked one wrong move away from floating away.

Izuku froze, his green eyes blown wide. But as he looked across the circle and met Katsuki's burning, unyielding gaze, something inside him snapped. The three years of running, of fighting side-by-side, of surviving wars and matching Katsuki step-for-step—it rose up, burning through his usual stuttering defense mechanism.

Izuku didn't slide back into the cushions this time. He didn't hide his face. Instead, a sudden, dizzying wave of bravery washed over him. He let out a slow, steady exhale, his shoulders dropping. He uncurled his legs, planting his feet firmly on the floor, and looked right back into Katsuki's eyes with a quiet, fierce intensity of his own. his gaze challenging.

Katsuki's eyes widened a fraction, a sudden spark of surprise flaring in the crimson depths at Izuku's unexpected defiance. A dark, heavy flush crept up Katsuki's neck, a visceral reaction to the silent challenge. He didn't hesitate.

Katsuki dropped to his hands and knees, crawling across the center of the circle. The movement was slow, deliberate, and entirely predatory, his broad shoulders shifting beneath his way too tight black t-shirt. The circle parted instantly, students scrambling backward to give them room.

He stopped directly over Izuku. The sudden, overwhelming weight of his presence pinned Izuku to the spot. Without a word, Katsuki reached out. His large, calloused hand wrapped around both of Izuku's wrists in a single, unyielding grip, pinning them flat against the carpet above Izuku's head.
The physical contact was electric. The hold wasn't very firm he could jump out at any time, but how could Izuku do that with this many people in the room.

Izuku's breath hitched, but he refused to look away. He stared straight up into Katsuki's face, his green eyes bright and entirely unfazed by the proximity.

Katsuki leaned down, his chest pressing slightly against Izuku's. The scent of caramelized sugar, whiskey, and raw ozone enveloped them completely. Katsuki's sharp jawline dipped, his lips brushing the shell of Izuku's ear.
The entire room held its breath. Nobody moved. Nobody breathed.

"You think you're fucking brave tonight, Deku?" Katsuki whispered, his voice a low, gravelly vibration that rattled straight down Izuku's spine. His hot breath fanned against the sensitive skin of Izuku's neck, sending a violent jolt of electricity through the smaller boy. "My unfiltered thought? I thought about how fucking good you looked. And how much I wanted to bite you right where the cream was, just to see if you'd make that pathetic, breathless sound for me again."

Izuku's composure shattered in a spectacular, instantaneous meltdown. The newfound bravery vanished, replaced by a blinding, uniform shade of crimson that flooded his face, his neck, and his ears. His heart battered against his ribs so violently he was certain Katsuki could feel it through their chests.

Katsuki pulled back just an inch, his crimson eyes scanning Izuku's completely burning face.
But as Katsuki took in the sight of Izuku's flushed cheeks and blown-out pupils, the weight of his own words seemed to catch up to him. Katsuki's smug, dominant expression suddenly faltered. A heavy, dark crimson blush violently erupted across Katsuki's sharp cheekbones also turning his ears a bright, furious red.

Katsuki blinked, suddenly looking thoroughly flustered by the sheer, unfiltered honesty of his own admission. His grip on Izuku's wrists loosened, his fingers twitching as if he had just touched a live wire.

For a second, the two powerhouse heroes of UA High just stared at each other from inches away, both of them completely red-faced, breathing heavily, and entirely trapped in the high-voltage web they had spun between themselves.
Katsuki abruptly shoved himself backward, breaking the contact. He scrambled to his feet, swiping a hand aggressively across his burning face, refusing to look back at the couch.

"Fucking stupid game," Katsuki growled, his voice cracking slightly with a rare, flustered tension as he stormed straight past the circle, grabbed his jacket from the back of the armchair, and walked out the balcony doors into the cool summer night, slamming the glass shut behind him.
The room remained in a state of absolute, paralyzed shock.

Izuku lay on the carpet for a few seconds longer, his hands still hovering above his head where Katsuki had pinned them. He slowly brought his hands down to cover his face, letting out a long, weak, trembling groan that was entirely muffled by his palms. He was completely short-circuited.

"Oh... my... god," Mina breathed, her eyes the size of flying saucers as she stared at the balcony doors, then back at Izuku. "I think... I think we just witnessed the birth of a new factor."

"Bro..." Kirishima managed, his jaw still slack. "That was... that was the most intense thing I've ever seen in my entire life. Are you still alive, Midoriya?"

Izuku just curled onto his side, his entire body radiating heat like a radiator left on in July. He could still feel the exact phantom pressure of Katsuki's hand around his wrists, and the gravelly, dark promise of his voice whispered directly into his ear.

The green bottle lay forgotten in the center of the floor, the party's chaotic energy completely permanently altered by the raw, unspoken truth that had just rewritten the gravity of the room.

 

The sudden, explosive departure of Katsuki into the humid summer night left the common room hanging in a state of suspended animation. The heavy glass balcony door hadn't just slammed shut; it had effectively sealed forty of UA High's top students inside a vacuum of pure, unadulterated bewilderment.

For a long, agonizing minute, the only sound was the low, electric hum of Kaminari's dwindling strobe light and the rhythmic shuff-shuff of Iida's broom in the far corner, which had slowed to a bewildered halt.

"Well," Monoma remarked, his voice cracking slightly as he desperately tried to retrieve his scattered aristocratic composure. He adjusted his wrinkled collar, though his eyes remained wide and fixed on the dark balcony. "It appears Class A's resident volcano has suffered a catastrophic thermal event. A predictable display of emotional volatility."

"Shut up, Monoma," Jiro muttered, though there was no real bite to her voice. She was staring at Izuku, her jacks twitching with a nervous, frantic energy. "I don't think that was an explosion. I think that was a meltdown."

In the center of the sofa, Izuku was still in a wierd state, his mind not even forming a single straight thought, his messy green curls were practically standing on end. The heat radiating from his collarbone felt tangible, a literal thermal output that had Uraraka hovering her hands over his shoulders, terrified to actually touch him.

"Deku" Uraraka whispered, her voice a mix of deep concern and high-pitched romantic panic. "Are you... do you need me to float you to the nurse's office? You look like you're about to pass out."

"I'm fine," Izuku's voice emerged as a muffled, choked squeak from between his knees. "I'm completely... the tactical density of this room is just very high right now..."

"He's speaking in tongues," Kaminari whispered to Sero, his face blanking into a look of profound awe. "Bakugo actually broke Deku's brain. Like, permanently."

Mina, however, was not about to let the momentum of the universe's most dramatic senior party die on a literal balcony threshold. Shaking off her shock with a sharp, feral grin, she slammed her hands onto the coffee table, her pink skin practically glowing under the fairy lights.

"Oh, no. No, no, no," Mina purred, her eyes flashing with a dangerous, late-night brilliance. "We are not ending the night on a dramatic exit. The tension in this room is thick enough to stop a bullet from Snipe. If we leave it like this, tomorrow's training session is going to end in actual casualties."

"Ashido, the structural integrity of the student body's sanity has already compromised!" Iida protested, finally abandoning his broom to march toward the center of the circle, his glasses flashing.

"Bakugo has exited the residential premises, and Midoriya is currently experiencing a severe stress-induced cognitive block! As Class Representative, I must advise that we transition to a standard, orderly bedtime routine!"

"Iida, my brave, cat-texting leader," Setsuna Tokage laughed, her sharp teeth gleaming as her hand detached from her wrist and floated over to pat Iida's cheek. "The bedtime routine is dead. Look at the clock."

The digital display on the common room microwave blinked a bright, neon 1:15 AM. The late hour had officially dissolved the last remaining barriers of teenage rationality.

"Tokage is right," Kendo sighed, rubbing her temples, though a small, helpless smile tugged at her lips. "If we go to bed now, nobody is sleeping. Monoma will spend the night analyzing the psychological subtext, Kirishima will feel guilty"

"So, what's the play, Ashido?" Sero asked, a wicked grin spreading across his face as he leaned back on his elbows. "We can't spin the bottle for Truth or Dare if the main target is out on the balcony acting like a gargoyle."

Mina reached behind her, pulling a dusty, unlabelled glass bottle from beneath the sofa cushions—a relic from some long-forgotten Class A cleaning day. She set it dead center on the floorboards, replacing the green glass botle.
"We transition to the ultimate phase," Mina announced, her voice dropping into a thrilling, dramatic whisper that had the entire circle leaning in once more. "Spin the bottle. But none of that kissing-on-the-cheek kid stuff. We are seniors. We have agencies waiting for us. We have licenses. It's time for Seven Minutes in Heaven."
A collective, thunderous gasp rippled through the combined classes.

"Seven minutes?!" Hagakure shrieked, her invisible sleeves flailing wildly in the air. "In the dark?! Ashido, that's... that's practically a pro-hero level hazard!"

"The rules are absolute!" Mina cheered, pointing toward the large, dark supply closet at the back of the common area—the one usually reserved for Sato's bulk flour bags and Sero's extra tape rolls. "The bottle spins. Whoever it points to, the spinner has to go into the closet with them for seven full minutes. No quirks, no phones, just raw, unfiltered communication. Or, you know... whatever else happens in the dark."

"A test of isolation!" Tokoyami intoned from his corner, his arms crossed over his chest. "A descent into the abyss where the truth cannot be cloaked by the shadows."

"Dark Shadow wants to go!" the quirk chirped, popping out from Tokoyami's cloak with a tiny pair of imaginary binoculars. "Let me spin! Let me spin!"
"Quiet, fool," Tokoyami muttered, pulling his collar up.

Before anyone could lodge a formal complaint—or before Iida could write a new thesis on residential code violations—Mina lunged forward and gave the glass bottle a vicious, echoing twist.
The heavy glass rattled against the hardwood floor, a much louder, deeper sound than the plastic bottle. It spun in a chaotic blur, reflecting the dim, amber fairy lights until forty teenagers were locked in a silent, agonizing countdown.

The bottle slowed, its base dragging... stuttering... past Kaminari... past Rin... before its neck clicked to a definitive stop.
The tip was pointing directly at Eijiro Kirishima.
"Ah! Me again?!" Kirishima yelled, his face turning bright red as he cracked his knuckles in sheer, defensive reflex. "Man, the universe is really targeting my chivalry tonight!"

"No backing out, Kirishima!" Mina laughed. "Now, spin it to find your partner in crime!"
Kirishima dragged himself forward, his red hair messy as he gave the glass bottle a determined, manly shove. The bottle whirled across the carpet, its momentum dying down much quicker this time. It skated past Class B's girls, knocked against Sato's foot, and finally slid to a halt.

The cap was pointing squarely at Tetsutetsu Tetsutetsu.
The room fell into a stunned, breathless silence, followed instantly by a roar of pure, unadulterated delight from Kaminari and Sero.
"YES! THE BROTHERHOOD!" Kaminari howled, slamming his hands against the floor. "THE ULTIMATE MATCH!"

Kirishima and Tetsutetsu stared at the bottle, then slowly looked up at each other. Instead of looking embarrassed, their expressions simultaneously hardened into a look of fierce, aggressive determination.

"Tetsutetsu" Kirishima yelled, standing up and throwing his shoulders back. "Seven minutes of pure, unfiltered strategic hero analysis. No distractions."
"Kirishima..." Tetsutetsu roared back, standing up so fast his metal chair rattled. "We're going to talk about our armoring techniques until the walls sweat! Let's go!"

The two of them marched shoulder-to-shoulder toward the supply closet like soldiers heading into battle. Sero aggressively shoved them inside, slamming the heavy wooden door shut and clicking Kaminari's phone timer.

"Seven minutes starts... now!" Mina called out.
For the next seven minutes, the common room was treated to the muffled, vibrating sounds of two extremely loud, metallic teenagers intensely debating the nutritional benefits of iron supplements and shouting encouragement at each other through the drywall.

"YOU GOTTA KEEP YOUR FORM TIGHT, BRO!" Kirishima's voice echoed faintly through the door.
"I AM TRYING, BRO! THE FLOUR BAGS ARE LIMITING MY RANGE OF MOTION!" Tetsutetsu yelled back.

When Sero finally threw the door open at the seven-minute mark, a cloud of white flour drifted out into the hallway. Kirishima and Tetsutetsu emerged, covered in dust, aggressively shaking hands and looking like they had just reached a new level of spiritual enlightenment.

"Incredible," Monoma muttered, wiping a stray speck of flour from his sleeve. "They managed to turn a romantic trope into a weightlifting seminar. Class A's capacity for missing the point remains unparalleled."

"Your turn to spin, steel-boy, choose who will have to find a partner!" Mina cheered, ushering Tetsutetsu toward the center of the room.
Tetsutetsu, still wiping flour from his eyebrows, dropped to his knees and gave the glass bottle an aggressive twist. The heavy glass screamed against the floorboards, its rapid rotation drawing everyone's eyes back to the epicenter of the drama.
The room had grown cooler now, a soft, summer breeze beginning to rattle the balcony doors where Katsuki had disappeared. The atmosphere was loose, hazy, and thick with the chaotic energy of the late hour.

The bottle began to slow. It skated past Momo, drifted past Kendo, and stuttered on a loose seam in the carpet.

With a heavy, final clack, the neck of the bottle pointed straight toward the sofa. Directly at Midoriya.
The collective air in the common room seemed to vanish for the third time that night. Izuku, who had only just recently emerged from his self-imposed knee-fortress, went completely rigid, his green eyes blowing wide as he stared at the glass tip resting inches from his sneakers.

"Oh, you've got to be kidding me," Jiro laughed, throwing her head back against the cushion. "The universe doesn't just have a sense of humor; it has a literal scriptwriter."

"Midoriya!" Mina gasped, her hands flying to her cheeks. "The wheel of fate has spoken! Spin it! Find out who is going into the abyss with you!"

The glass bottle lay dead center on the floorboards, its heavy base casting a long, sharp shadow under the low amber glow of the fairy lights. Izuku stared at it, his throat completely dry. His hands, still slightly trembling from the phantom pressure of Katsuki's grip on his wrists, clutched at his knees.

"Midoriya!" Mina gasped, her hands flying to her cheeks as a dangerous, manic spark flared in her dark eyes. "The wheel of fate has spoken! Spin it! Find out who is going into the abyss with you!"

"I really don't think—" Izuku stammered, his face instantly reigniting into a familiar, violent shade of crimson. "The statistical probability of me being chosen three times in a row under different parameters is—"

"Spin! Spin! Spin!" the common room chanted in a low, rhythmic rumble, led entirely by Kaminari and Sero, who were beating a frantic tattoo against the floorboards.

Realizing there was absolutely no escape from the collective peer pressure of thirty-nine sleep-deprived teenagers, Izuku dragged himself forward on his knees. He reached out a shaking, scarred hand, his fingers brushing the cold glass of the neck. With a frantic, self-defensive flick of his wrist, he sent the bottle into a ferocious, blurring spin.

The glass screamed against the hardwood. Forty pairs of eyes tracked the reflection of the fairy lights dancing across its surface. It slowed down, dragging its base... past Uraraka... past Todoroki—who watched with a look of intense, clinical curiosity—past Kendo... before its neck stuttered to a definitive, heavy stop.

The tip was pointing directly at Mina Ashido.
Mina blinked, her jaw dropping before a wide, wildly chaotic grin split her pink face. "Oh! The puppet master becomes the puppet! Alright, Midoriya, let's see what the dark has to offer!"

Before Izuku could even process the sheer panic flooding his system, Mina hopped off the coffee table, grabbed him by the forearm, and hauled him toward the supply closet. Sero was already standing by the door, grinning like a goblin as he ushered them inside the narrow, flour-dusted space.

"Seven minutes! No quirks, no cheating!" Kaminari shouted, slamming the heavy wooden door shut.
The click of the lock sounded like a prison sentence.

The darkness inside the closet was absolute, smelling strongly of spilled baking flour, cardboard boxes, and the sweet, citrusy berry scent of Mina's perfume. Izuku stood rigid against a stack of storage crates, his heart hammering against his ribs so loudly he was certain she could hear it. Why is the bottle targeting him.

"Ashido," Izuku whispered, his voice lowering in the pitch black. "We can just... we can just talk-"

"Shh! Don't say anything," Mina's voice cut through the dark, remarkably close. "Just hold still for a second."

Izuku froze, his breath catching in his throat. He heard the faint, metallic rustle of her jacket pockets, followed by the distinct, plastic snap of a lid being removed.

Suddenly, the small, bright screen of Mina's phone illuminated from below, casting a soft, pinkish glow over her mischievous expression. She wasn't looking at him with romance; her eyes were flashing with pure, unadulterated theatrical malice. In her hand, she held a sleek tube of heavy, cherry-red lipstick.

"Ashido?" Izuku blinked, thoroughly baffled.
"What are you doing with—"

"I am saving this party from a boring ending, Midoriya," Mina whispered, a wicked grin spreading across her face. She stepped closer, using her left hand to forcefully ruffle his already messy green curls, pulling a few strands over his forehead to make him look thoroughly disheveled.
Before he could protest, Mina twisted the tube, heavily coating her lips in the bright, glossy crimson wax. She smacked her lips together with a sharp pop, then grabbed Izuku by the shoulder, pulling him down to her height.

"Hold perfectly still. If you move, I'll get it in your hair," she ordered.

Mina leaned in, deliberately planting a firm, glossy kiss directly on the side of Izuku's neck, right over his pulse point. The cold, waxy texture made him flinch, a tiny, strangled gasp escaping his throat. She pulled back, evaluated her handiwork in the faint glow of the phone screen, and leaned in again, pressing three more distinct, overlapping lip marks across his jawline and high on his flushed cheek.

"Perfect," Mina giggled, wiping her mouth with the back of her sleeve, leaving a faint smudge of pink on her skin. "Now, when we go out there, you just keep your mouth shut and look overwhelmed.
Which, honestly, you already do."

"You want them to think we...?" Izuku's brain completely short-circuited, the sheer tactical complexity of her psychological warfare leaving him entirely stranded.

"Psychological warfare, Midoriya," Mina whispered, turning off her phone screen and plunging them back into the dark. "It's a crucial hero skill."

Outside, the heavy glass balcony doors slid open with a soft, muted click.
Katsuki walked back into the common room. The cool summer breeze had apparently done its job; the explosive, erratic tension that had sent him storming out was gone, replaced by his usual, low-burning scowl. His sharp cheekbones were no longer flushed, and he had thrown his dark jacket over his shoulders, looking completely cooled down and steady.

He didn't say a word as he crossed the room, but the ambient chatter instantly dipped. He reclaimed his spot by the base of the armchair, crossing his arms over his chest as his crimson eyes swept the circle.

"Oh, look who decided to grace us with his explosive presence," Monoma muttered from behind Shishida, though he kept his voice noticeably quiet.
Katsuki ignored him entirely. His eyes automatically flicked toward the sofa, searching—and instantly narrowing when he realized the green-haired center of his attention was missing.

*Click.*

The supply closet door flew open. Sero stood there, holding Kaminari's phone aloft. "Time's up, roomies! Let's see who survived the—"
Sero's voice died in his throat.

Mina stumbled out first, dramatically wiping the corner of her mouth with a flushed, breathless laugh, her pink skin glowing as she ruffled her own hair. Right behind her, Izuku emerged, looking like he had just been hit by a localized tornado. His green curls were completely wild, sticking up in every direction, his shirt was slightly tugged at the collar, and his face was a uniform, blinding shade of sunburned crimson.

But it was his skin that drew the collective, suffocating gasp from the room.
Clearly visible under the bright fairy lights were three distinct, deep cherry-red lipstick stains stamped boldly along his jawline, and one prominent, glossy mark pressed right over the side of his neck.

"Oh my god," Jiro whispered, her headphone jacks dropping flat against her shoulders.
Uraraka's jaw dropped so low it looked painful. Even Todoroki paused, his hand hovering halfway to his mouth with a fresh liquor box, his mismatched eyes widening a fraction.

Across the room, the temperature didn't just drop—it plummeted into an absolute arctic freeze.
Katsuki's entire body went rigid. The casual, cooled-down posture vanished instantly, his shoulders squaring as his grip tightened against his own arms so hard his knuckles turned white. His crimson eyes locked onto the bright red marks on Izuku's neck with a fierce, terrifying intensity. He didn't explode. All he could do was just stare, a heavy, suffocating wave of pure, unadulterated jealousy radiating off him like raw heat. The line of his jaw set into marble, his teeth grinding together with a faint, audible click.

Izuku caught Katsuki's look and instantly felt the phantom tracks on his stomach flare up like fire. He desperately tried to pull his collar up to hide the marks, his ears burning so hot he was certain they were smoking from this fucking party.

"How could you Midoriya... The bro code man..." was all that Mineta could stutter out before getting his face slapped by Tsu.

"Well, well, well," Kaminari broke the paralysing silence, a wicked, vengeful grin spreading across his face as he looked from Izuku's stained neck straight to Katsuki's murderous expression. This was payback for the balcony stunt. This was payback for the three years of explosive threats.
Kaminari lunged across the carpet, grabbing the heavy glass bottle and thrusting it directly into Katsuki's personal space, holding it out like a challenge.

"You walked out on the game, Bakugo, but you don't get off that easy," Kaminari crowed, his voice laced with absolute defiance. "Rule number one of UA High senior night: nobody leaves the circle without paying their dues. You owe the room a spin."

Katsuki's eyes didn't leave Izuku's face for a single second. The silence stretched tight, heavy with an unspoken, territorial tension that had the entire room sweating through their clothes. Slowly, deliberately, Katsuki reached down, his fingers wrapping around the neck of the glass bottle.
"Fine," Katsuki growled, his voice a low, gravelly vibration that promised literal devastation. "Watch the bottle, Deku." It sent chills down his whole body.

The heavy glass bottle caught the dim, amber glow of the fairy lights as Katsuki's fingers tightened around its neck. The tension in the room was a physical weight, thick and suffocating, suffocating everyone except Kaminari, who was riding the high of his own sheer, reckless bravery.

With a sharp, violent snap of his wrist that looked like he was trying to crack the floorboards, Katsuki sent the bottle spinning.

The glass screamed against the hardwood. It was a ferocious, blurring rotation that drew forty pairs of eyes down to the center of the floor. It spun past Kaminari, past Todoroki, past the couch where Izuku sat completely paralyzed under the weight of those crimson eyes. The momentum began to die down, dragging its heavy base in a stuttering rhythm until it finally clicked to a dead stop.
The neck of the bottle was pointing directly at Pony Tsunotori.

Pony blinked, her large blue eyes widening in sudden, absolute panic. She looked at Katsuki, whose scowl was so intensely dark that a faint trace of smoke seemed to be curling from his clenched fists.

"Ah! Me?!" Pony squeaked, her accent thick as she instinctively shuffled backward, her hooves clicking frantically against the floor. "In the closet? With the explosion man? Oh, *non, non*, I am too young to be blasted into orbit!"

Before Mina or Kaminari could even enforce the rules, Ibara Shiozaki stepped forward, her vine-like hair bristling protectively around Pony's shoulders. "The Lord commands us to flee from wrath and destruction! I cannot allow an innocent lamb to be led into the den of a roaring lion. Look upon his countenance—he is a vessel of pure fury!"

"Hey! I'm right here, vine-head!" Katsuki snarled, his voice a low, dangerous rumble.

"See?!" Pony gasped, practically hiding behind Shishida's massive bulk. "My English is failing me from the fear! I cannot do the seven minutes! I forfeit my citizenship!"

"A technical disqualification!" Monoma announced, though he took a strategic step backward himself. "Class B's preservation instincts remain far superior to Class A's suicidal tendencies. The spin is void!"

"Aw, come on!" Kaminari groaned, though he wisely didn't push the matter with a terrified Pony. He turned back to Katsuki, thrusting a finger toward the floor. "Rules are rules, Bakugo! A void spin means you have to spin again! No exceptions!"

Katsuki's jaw set into a rigid, furious line. His teeth ground together with a faint, audible click. He didn't care about the girl, he didn't care about the rules, and he certainly didn't care about Kaminari's petty defiance. But as his eyes flicked back across the radius of the circle, they locked right onto the deep cherry-red lipstick stains stamped boldly along Izuku's jawline. The sight of it sent a savage, territorial spike of pure jealousy straight through his chest. He couldn't let Izuku off the hook so easily.
