Chapter Text
The app is called OmegaMatch Pro, and Leo hates everything about it.
Hates the clean white interface, hates the way it asks invasive questions about his heat cycle and scent profile, hates the little animation of two wolves nuzzling that plays while it "finds your perfect biological match." He especially hates that he's sitting in Junmin's apartment at eleven on a Tuesday night, watching his friend fill out the profile for him because Leo keeps closing the app in disgust.
"You're being a baby," Junmin says, sprawled across his couch with Leo's phone held hostage. His fingers fly across the screen. "This is exactly what you need."
"I don't need anything." Leo takes another sip of soju, feels it burn down his throat. "I'm fine."
"You're sexually frustrated and you smell like it." Junmin doesn't even look up. "Last week you called me at three in the morning complaining about another alpha who couldn't find your prostrate."
Leo's ears burn. "He said he was experienced—"
"He asked you to top him fifteen minutes in."
"I know!" Leo groans, pressing his palms to his eyes. "I know, okay? I know I look like—like I should be the one in control, but I'm not, I just—I need—"
"You need someone who can actually dom you," Junmin finishes, finally looking up. His expression is softer now, sympathetic. "Someone who sees that you're a omega who wants to submit, not perform. Someone who won't be intimidated by your face or your image or whatever complex they have about omega stereotypes."
Leo's throat feels tight. He takes another drink instead of answering.
Because Junmin is right, which is the worst part. Leo is an omega, yes, but he's also six feet tall with sharp features and a dancer's build, all lean muscle and controlled grace. Every alpha he's been with takes one look at him and assumes he wants to be in charge, wants to be worshipped, wants to do the work. And Leo is so tired. So fucking tired of alphas who can't just pin him down and take, who can't read that when he gets mouthy it's because he wants to be shut up, who mistake his frustration for disinterest.
He's needy. He's so needy it makes him feel pathetic. He wants to be held down and fucked until he can't think, wants an alpha who will make decisions for him, wants to feel small even though he's not.
But he doesn't want a bond. Not yet. Maybe not ever. He likes his freedom, likes his space, likes not being tied to someone's instincts and expectations.
Which makes him, apparently, impossible to match.
"Okay, done." Junmin sounds triumphant. "I answered all the questions honestly—yes, you're a bottom, yes, you're submissive, yes, you produce high-grade omega pheromones, yes, you're looking for no-strings-attached arrangements—"
"You didn't."
"I did." Junmin grins, feral. "And now we wait for—oh. Oh."
"What?" Leo sits up too fast, soju sloshing in the bottle. "What is it?"
Junmin's eyes are huge. He turns the phone around slowly.
The screen shows a profile. The first thing Leo sees is the photo—a man in a pool, water streaming down his face, blonde hair darkened by chlorine, shoulders that look like they were carved from marble. His expression is serious, almost cold, but there's something compelling about the set of his jaw, the intensity in his eyes.
Lee Sangwon, 22, Alpha Occupation: Professional Swimmer, National Team
Looking for: Omega partner for pheromone desensitization therapy
Notes: I have omega pheromone disorder. Most omega scents trigger severe allergic reactions (migraines, nausea, respiratory issues). My doctor recommended controlled exposure through an app-matched partner. This is medical, not romantic. Compensation negotiable.
Match Compatibility: 98.7%
Leo reads it twice. Then a third time.
"He's fucking gorgeousss," Junmin whispers. "And he's offering to pay you to hang out with him?"
"It says medical." Leo's brain is still catching up. "He has a disorder."
"So? You're not looking for romance anyway." Junmin is already tapping the screen. "And look at this face, Leo. Look at it. This is a man who could throw you around a room."
Leo snatches the phone back. Studies the photo again. There's something about Sangwon's expression that makes his omega hindbrain sit up and pay attention—a particular brand of controlled intensity, like he's holding himself back. Leo wonders what he'd look like letting go.
His finger hovers over the MATCH button.
"It's just for his medical condition," Leo says, half to himself. "It's not—he probably won't even like my scent. Most alphas think citrus is too sharp."
"Only one way to find out."
Leo closes his eyes. Presses the button.
The app makes a cheerful pinging sound, and the screen fills with golden sparkles.
MATCH CONFIRMED! Lee Sangwon has accepted your profile. Start chatting now?
"He accepted immediately," Junmin shrieks, grabbing Leo's arm. "Oh my god, he was waiting, he wanted—"
A message pops up.
LSW: Can we meet tomorrow? I have training at 6am but I'm free after 10. There's a café near Olympic Park. I'll send the address.
Leo's heart kicks against his ribs.
LSW: I should mention that I've tried this before with other omegas and it didn't work. Their scents all made me sick within five minutes. If that happens with you, I'll still pay for your time. My manager insists on compensating people properly.
LSW: But I hope it doesn't happen.
Leo stares at the messages. There's something almost vulnerable in that last line, buried under the blunt professionalism.
His fingers move before his brain catches up.
LLO: Tomorrow works. 10am is fine. And you don't have to pay me if it doesn't work out.
LLO: But I hope it doesn't happen either.
He watches the typing indicator appear, disappear, appear again.
LSW: See you tomorrow, then.
LSW: Thank you.
Leo locks his phone. Looks at Junmin, who is vibrating with excitement.
"I have a date," Leo says, numb.
"You have a medical appointment with the hottest alpha I've ever seen who has a job and muscles and apparently doesn't make you want to throw yourself off a bridge." Junmin raises his soju bottle. "I'm a genius. You're welcome."
Leo knocks their bottles together, drinks, and tries not to think about how his omega instincts are already purring at the thought of tomorrow.
The café is small, tucked away from the main street, all exposed brick and plants hanging from the ceiling. Leo arrives ten minutes early because he's anxious, orders an iced americano because he needs something to do with his hands, and claims a corner table where he can see the door.
He's wearing his usual—black jeans, an oversized cream sweater, silver rings on his fingers. He didn't try to dress up because this isn't a date, it's a medical consultation, but he still checked his hair four times in the mirror and made sure his scent blockers were only at half strength.
If Sangwon has omega pheromone disorder, he needs to actually smell Leo. Which means Leo needs to be vulnerable in a way that makes his skin prickle with nervousness.
At 10:03, the door opens.
Sangwon walks in, and Leo's brain shorts out.
Because the photos didn't do him justice. In person, he's devastating—taller than Leo expected, shoulders broad enough to block out the sun, moving with the easy confidence of someone who's completely in control of his body. He's wearing a simple black tracksuit, his blonde hair still slightly damp from the pool, and when his eyes scan the café and land on Leo, something in his expression shifts.
His nostrils flare. His pupils dilate. He goes very, very still.
Leo can see the exact moment Sangwon scents him from across the room.
Then Sangwon is moving, crossing the café in long strides, and Leo barely has time to stand before the alpha is right there, towering over him, close enough that Leo can smell him back—chlorine and something crisp, cedar and frost, aggressive and clean.
"You're Leo." Sangwon's voice is deeper than Leo expected, rough around the edges.
"Yes." Leo's own voice comes out steadier than he feels. "You're Sangwon."
"I am." Sangwon is still staring at him, intense and unwavering. "Can I—I need to—"
He leans in.
Leo's breath catches as Sangwon dips his head, gets close to Leo's neck, and inhales. It's invasive and intimate and should probably be illegal in public, but Leo can't move, can't breathe, can only stand there as this alpha scents him thoroughly.
Sangwon makes a sound low in his chest. His hands twitch at his sides like he wants to reach out.
When he finally pulls back, his expression is shell-shocked.
"You smell like clean laundry in summer," Sangwon says, rough and wondering. "Milk and linen and—something citrus, but it's not sharp, it's soft, it's—" He cuts himself off. "I don't feel sick."
Leo's heart is pounding. "That's good?"
"That's—" Sangwon laughs, and it sounds incredulous. "Do you know how many omegas I've met with in the last six months? Fourteen. Fourteen different scents, all of them made me want to claw my own nose off. But you—" He shakes his head. "You're perfect."
The word hits Leo like a physical thing. His omega preens, delighted, and he has to physically wrestle the reaction down.
"Should we sit?" Leo manages.
Sangwon blinks like he's just remembering they're in public. "Right. Yes. Sorry."
They sit. Sangwon's knees bump Leo's under the small table, and neither of them moves away.
"So," Leo starts, wrapping his hands around his coffee. "Your profile said you need exposure therapy?"
"My manager set that up." Sangwon runs a hand through his hair, and Leo tracks the movement. "He's—persistent. The Olympics are in eight months, and I can't afford to have an attack every time I'm near omega teammates or competitors. The doctor said controlled, repeated exposure to a compatible omega scent might help desensitize me."
"But it has to be a compatible scent."
"Exactly." Sangwon's eyes are on him again, that intense focus that makes Leo feel pinned. "And yours is—I've never smelled anything like it. I want to—" He stops. "Sorry. I'm being weird."
"You're fine." Leo takes a sip of coffee to buy himself time. "What do you want?"
Sangwon's gaze sharpens. "What do you mean?"
"You said you want to." Leo keeps his voice level. "Want to what?"
A pause. Then, low and honest: "Get closer. Bury my face in your neck and breathe you in until I'm fucking dizzy with it." Sangwon's jaw clenches. "Which is insane because I've known you for five minutes, but I can't—you smell so good, Leo."
Heat floods Leo's body. His omega instincts are screaming yes, alpha wants us, alpha likes our scent, and he has to dig his nails into his palms to stay grounded.
"The app said we're 98.7% compatible," Leo says. His voice has gone lower, rougher. "I didn't know it could be that high."
"It can't. Usually." Sangwon leans forward, elbows on the table. "The highest I've seen before was 60%, and that omega still made me sick. But you—" His eyes drag over Leo's face. "What are you looking for? Your profile said no bonds."
"I don't want to be mated," Leo confirms. "I want—" God, how does he explain this? "I need an alpha who can give me what I need without the biological lock-in. Someone who understands that I'm omega but I don't fit the stereotype. Someone who won't expect me to be soft and delicate just because of my designation."
"You look like you could break someone in half."
Leo's surprised into a laugh. "Most alphas are intimidated by that."
"I'm not." Sangwon's voice drops another register. "I like it. Makes me want to prove I can handle you."
The air between them crackles. Leo feels heat building at the base of his spine, his omega responding to the challenge in Sangwon's tone.
"Handle me?" Leo raises an eyebrow.
"Pin you down." Sangwon says it casually, like he's discussing the weather. "Make you stop thinking so hard. You look like you think too much."
"I—" Leo's breath hitches. "You don't even know me."
"I know you're an omega who doesn't want to be treated like glass." Sangwon tilts his head. "I know you matched with me even though my profile made it clear this is medical necessity, which means you're practical. I know you're wearing scent blockers at half-strength, which means you wanted me to smell you but you're still cautious. And I know—" His eyes drop to Leo's hands. "I know you've been digging your nails into your palms since I said I wanted to scent you, which means you're turned on but trying to hide it."
Leo's face flames. He uncurls his fingers, sees the little half-moon marks in his skin.
"You're observant," he says, aiming for dry and landing somewhere breathless.
"I'm an athlete. Observation is survival." Sangwon reaches across the table, and Leo's breath stops as those large hands wrap around his, gentle and firm. "Your profile said you're looking for a dom alpha. Is that accurate?"
Leo can't look away from where they're touching. "Yes."
"And you've never found one who could give you what you need."
"They all—" Leo swallows. "They think I want to be worshipped. Put on a pedestal. But I don't, I just want—"
"To be taken apart," Sangwon finishes. His thumbs stroke over Leo's knuckles. "To submit without losing yourself. To be held down and fucked until you can't remember your own name."
Leo makes a strangled sound. His omega is keening, desperate, yes yes yes.
"How do you—" Leo's voice cracks. "How do you know?"
"Because that's what I want to do to you." Sangwon says it simply, matter-of-fact. "From the moment you stood up and I saw how tall you are, how strong, all I've been thinking about is how good you'd look underneath me. Pinned and wanting and mine."
"We just met," Leo says weakly.
"I know." Sangwon's grip tightens. "Tell me to stop and I will. Tell me I'm reading this wrong and we can go back to talking about medical treatments and compensation."
Leo looks at him. Really looks. Sees the tension in Sangwon's shoulders, the way his alpha instincts are clearly clawing at him, the white-knuckled control he's exerting.
A tsundere alpha, his profile had said. Nonchalant. But there's nothing nonchalant about the way Sangwon is looking at him now—like Leo is something rare and precious and edible all at once.
"You're not reading it wrong," Leo hears himself say. "I want—I need—"
"Tell me." Sangwon's voice is pure command, and Leo's spine goes liquid.
"I need you to prove it." The words spill out. "I need you to show me you can actually handle me, that you won't get scared when I push back, that you can—" He breaks off, panting.
Sangwon stands up. Still holding Leo's hand.
"Come with me."
"Where—"
"My apartment. It's ten minutes away." Sangwon's eyes are dark, pupils blown. "I'm going to scent you properly. And then I'm going to see exactly how much you can take."
Leo should say no. Should be cautious, should remember this is a stranger, should use his brain instead of his biology.
But his omega is screaming alpha, perfect, need, and Leo has spent so many years ignoring his instincts that he's forgotten what it feels like to be wanted like this—desperately, immediately, correctly.
He stands up. Lets Sangwon pull him toward the door.
"Okay," Leo whispers. "Show me."
Sangwon's smile is sharp and promising and makes Leo's knees weak.
"I will, omega. I promise."
Sangwon's apartment is sleek and minimal—floor-to-ceiling windows overlooking the Han River, furniture in shades of grey and black, everything precisely organized. It smells like him, that chlorine-cedar-frost combination, and Leo's omega instincts immediately relax at being in an alpha's space.
The door clicks shut behind them.
For a moment, they just stand there. The air feels charged, crackling with pheromones and possibility.
Then Sangwon moves.
He crosses the space between them in two strides, backs Leo up against the door, and finally—finally—gets his hands on him. One palm flat against the door beside Leo's head, the other curling around his hip, possessive and sure.
"Tell me your limits," Sangwon says, low and rough.
Leo's brain is melting. "What?"
"Limits. What you don't want." Sangwon dips his head, noses along Leo's jaw. "I'm going to scent you and touch you and if you let me, I'm going to fuck you, but I need to know where the lines are."
"I—" Leo gasps as Sangwon's mouth finds his pulse point. "No biting. No mating marks. I told you, I don't want—"
"No bonds," Sangwon agrees. "I heard you. What else?"
"Safe word is red." Leo's hands come up to grip Sangwon's shoulders. "And I need—I need you to not hold back. Everyone always holds back."
Sangwon pulls away just enough to look at him. "You want it rough."
"I want to feel it." Leo meets his eyes. "I want you to make me submit. Actually make me, not just—ask nicely and hope I cooperate."
Something dangerous flickers across Sangwon's face. "You want me to earn it."
"Yes."
"You want to fight me."
Leo's breathing is ragged. "Yes."
Sangwon's hand slides from Leo's hip to his throat. Not squeezing, just resting there, a promise. "Then fight me, omega. Let's see if you can."
He kisses him.
It's not gentle. It's claiming, demanding, Sangwon's mouth hot and insistent against his, and Leo opens for him with a moan he can't suppress. Sangwon tastes like mint toothpaste and alpha, and when his tongue slides against Leo's, it sends electricity down his spine.
Leo kisses back hard, bites at Sangwon's lower lip, feels the alpha growl against his mouth. The hand on his throat tightens just slightly—a warning, a question—and Leo arches into it, needing more.
"Bedroom," Sangwon mutters against his lips. "Now."
"Make me," Leo shoots back, because he meant it when he said he wants to fight.
Sangwon's eyes flash. Then he's moving, bending down and getting his shoulder into Leo's stomach, hauling him up in a fireman's carry like he weighs nothing.
"Hey—!" Leo's protest turns into a yelp as Sangwon's hand comes down on his ass, sharp and stinging.
"You asked for this," Sangwon reminds him, already walking. "Don't pretend you don't want it."
Leo's face is burning. He's dangling over an alpha's shoulder, being carried to bed like a prize, and his omega biology is singing with it. He tries to struggle on principle, but Sangwon just tightens his grip and delivers another slap to his ass that makes Leo gasp.
The bedroom is as minimalist as the rest of the apartment—huge bed with dark grey sheets, blackout curtains, no clutter. Sangwon deposits Leo on the bed and follows him down, covering his body with his own, and—
Oh.
Leo has never felt small in his life, but Sangwon's shoulders block out the light, his weight is solid and grounding, and when he gets his hands on Leo's wrists and pins them above his head, Leo's entire body goes hot.
"Still want to fight?" Sangwon asks. His voice is a rumble in his chest.
Leo tries to pull his hands free. Sangwon doesn't budge.
"That's cute," Sangwon says. "Try harder."
Leo does. He's strong, he's a dancer, he has core strength and control, but Sangwon is an Olympic-level swimmer with shoulders built for power, and no matter how Leo struggles, he can't break the hold.
It makes him frantic. Makes him desperate. Makes slick start to gather between his thighs because finally, finally, here's an alpha who can actually hold him down.
"There you go," Sangwon murmurs, watching his face. "That's what you needed, isn't it? To know you can't win."
"Fuck you," Leo gasps.
Sangwon grins. Leans down and bites Leo's jaw, not hard enough to mark but enough to sting. "You will, omega. But first—"
He shifts his grip, gets both of Leo's wrists in one hand, and uses his free hand to push up Leo's sweater. Exposes his stomach, his ribs, the muscles he's built through years of dance.
Then Sangwon puts his mouth on Leo's scent gland and sucks.
Leo nearly arches off the bed. The sensation is overwhelming—Sangwon's mouth hot and wet, tongue laving over the sensitive gland, teeth grazing just enough to make Leo's vision blur. Omega pheromones flood the room, milk and citrus and desperate need, and Sangwon makes a sound like he's starving.
"God," Sangwon groans against his throat. "You taste as good as you smell. I could do this for hours."
He does. He scents Leo thoroughly, mouth dragging over his neck and collarbone and chest, hands mapping every inch of exposed skin, and Leo stops fighting and just takes it, head thrown back, wrists still pinned, letting himself be explored and claimed and worshipped in a way that doesn't feel like performance.
This feels like Sangwon is learning him. Memorizing him. Preparing to ruin him.
When Sangwon finally pulls back, his lips are slick and his eyes are black with want.
"I'm going to undress you now," he says. "And you're going to let me. Understand?"
Leo nods, boneless and needy.
"Words, omega."
"Yes." Leo's voice is wrecked. "Yes, I understand."
"Good boy."
The praise shoots straight to Leo's cock. He whimpers as Sangwon releases his wrists and starts stripping him efficiently—sweater over his head, jeans unbuttoned and peeled down his legs, until Leo is lying there in just his black boxer-briefs with an obvious wet spot at the front.
Sangwon sits back on his heels, still fully clothed, and just looks.
"You're beautiful," he says finally. "I want to take a picture so I remember this exact moment."
Leo's never been called beautiful in a way that felt true. Handsome, sure. Striking. Sharp. But beautiful?
"You're still dressed," he points out, breathless.
"I know." Sangwon's hands go to the zipper of his tracksuit. "Wanted to see you first. Wanted to make sure you're real."
He strips. Peels off the jacket and the shirt beneath, and Leo's mouth goes dry because Sangwon's body is ridiculous—all carved muscle and golden skin, shoulders impossibly broad, tapered waist, the deep V of his hips disappearing into his waistband.
When he shoves down his pants and boxer-briefs, Leo stops breathing.
Because Sangwon is hung. Thick and flushed and already hard, and Leo's omega biology does the mental math and sends a fresh wave of slick south.
"Like what you see?" Sangwon's mouth quirks.
"You know I do," Leo mutters.
Sangwon crawls back over him, settles between his thighs, and grinds down. The friction of their cocks rubbing together through the thin fabric of Leo's underwear makes them both groan.
"I'm going to prep you," Sangwon says against his mouth. "Going to get you open and desperate. And then I'm going to fuck you until you can't remember any of those other alphas who disappointed you. Okay?"
"Okay," Leo breathes. "Yes, please—"
Sangwon kisses him again, deep and filthy, while his hand slides down Leo's body and into his underwear. When his fingers find the slick mess between Leo's thighs, he makes a sound like he's been punched.
"You're soaked," he mutters. "Fuck, omega, how are you this wet already?"
"You—" Leo can't finish the sentence because Sangwon's fingers are circling his rim, teasing, gathering slick. "You pinned me down, you—ah—!"
One finger slides in, easy and slick, and Leo's back arches. Sangwon adds a second almost immediately, scissors them apart, and Leo clutches at his shoulders and tries to remember how to breathe.
"So tight," Sangwon murmurs. He's watching Leo's face like it's a religion. "So hot inside. You're going to feel incredible around my cock."
"Then hurry up," Leo gasps.
Sangwon's eyes flash. He adds a third finger, crooks them up, and nails Leo's prostate dead-on.
Leo's vision whites out. He makes a sound he's never made before, high and broken, and Sangwon does it again, again, until Leo is writhing and begging and completely gone.
"That's it," Sangwon praises. "That's perfect, baby, let me see you fall apart."
"Sangwon—please—I need—"
"I know what you need." Sangwon pulls his fingers out, and Leo whines at the loss. "Condom?"
"Implant," Leo gasps. "I have an implant, I'm clean, please just—"
Sangwon kisses him hard. "Me too. Clean. Tested last week." He lines himself up, the head of his cock pressing against Leo's rim. "Ready?"
Leo wraps his legs around Sangwon's waist. "If you don't fuck me right now I'm going to lose my mind."
Sangwon laughs, low and dark. Then he pushes in.
The stretch is incredible. Leo's body opens for him, slick-wet and eager, and Sangwon sinks in slowly, inch by inch, until he's fully seated and they're pressed together hip to hip.
For a moment, neither of them moves. They just breathe, foreheads pressed together, adjusting to the overwhelming sensation of being connected.
"Okay?" Sangwon's voice is strained.
"Move," Leo demands. "Alpha, please move—"
Sangwon pulls out halfway and slams back in.
Leo sees stars. He claws at Sangwon's back, mouth falling open, and Sangwon sets a brutal pace—deep, hard, exactly what Leo's body is screaming for. The bed frame creaks. The sound of skin on skin fills the room. Leo can't think, can't do anything but hold on and take it.
"This what you needed?" Sangwon growls against his ear. "Needed an alpha who could fuck you like this?"
"Yes—god, yes, don't stop—"
"Not stopping." Sangwon gets a hand under Leo's knee, pushes his leg up and back, changes the angle. "Going to ruin you for anyone else. You're mine now, omega. Say it."
"Yours," Leo gasps. "Yours, alpha, I'm—fuck—"
Sangwon nails his prostate again, and Leo's orgasm crashes over him without warning. He comes untouched, spilling between their bodies, clenching down hard on Sangwon's cock, and the alpha snarls and follows him over, spilling deep inside as his hips stutter.
They collapse together, panting and wrecked. Sangwon carefully pulls out, and Leo whimpers at the loss, feels come and slick trickling down his thighs.
"Holy shit," Leo manages.
"Yeah." Sangwon sounds equally destroyed. He rolls them onto their sides, tucks Leo against his chest. "That was—"
"If you say that was just okay I'm going to kill you."
Sangwon laughs. Presses a kiss to Leo's sweaty temple. "I was going to say that was the best sex of my life and I need at least ten minutes before I can go again."
Leo's omega purrs, satisfied. He burrows closer, breathes in Sangwon's scent—still cedar and frost but now mixed with sex and satisfaction.
"Your pheromone disorder," Leo says after a moment. "Did I—?"
"You're perfect." Sangwon's arms tighten around him. "I don't feel even a hint of nausea. Just—" He breathes in deep. "Just want more of you."
"We should probably talk," Leo says. "About logistics. Arrangements. What this is."
"Later." Sangwon kisses his shoulder. "Right now I'm going to hold you, and then I'm going to fuck you again, and somewhere in there we'll eat food and drink water like functional humans."
Leo should protest. Should be responsible. Should remember this started as a medical arrangement.
But Sangwon's hands are gentle on his skin, and for the first time in years, Leo feels satisfied, and maybe—just maybe—this is exactly what they both needed.
"Okay," he whispers. "Later."
Sangwon hums, content. Outside the window, Seoul continues on. But here, in this bed, there's just the two of them—a broken alpha and a misunderstood omega, finally finding something that fits.
