Deviation from Expected Outcome

Summary:

After a failed mission, Chuuya Nakahara returns to the Port Mafia carrying more than just casualties.

Osamu Dazai is waiting for him with a prank.

Things Donʼt go as planned.

Work Text:

The fluorescent lights hummed their eternal, tuneless song down the corridor of the Port Mafiaʼs east wing. At this hour, past midnight, edging toward the bleakest hours of morning, even the headquarters of Yokohamaʼs most feared criminal organization took on the hush of a mausoleum.

The wood paneling swallowed what little light the fixtures offered, casting long shadows that stretched like reaching fingers across the polished floor.

Dazai crouched behind a decorative console table approximately fifteen feet from Chuuyaʼs office door, his knees drawn up and a grin splitting his face like a wound. In his hands, he held a small mirror angled to catch the reflection of the doorframe, specifically, the metal bucket perched atop it, glinting with malicious promise.

Perfect, he thought, shifting his weight silently. The bucketʼs position was flawless. One inch to the left and it would tip prematurely; one inch to the right and it would catch on the doorʼs edge. But Dazai had calibrated it with the same precision he applied to far deadlier schemes, ensuring the bucket would remain stable until the door swung open precisely fourteen degrees, the exact point of no return.

The anticipation was delicious. Dazai had been waiting for nearly forty minutes, ever since the terse radio chatter from the mission squad confirmed their return, sans the target, sans the intelligence, and heavy with casualties.

He could already picture it: Chuuya storming down the corridor, practically vibrating with frustrated energy, his small frame taught as a bowstring. The door would fly open, the bucket would upend, and a cascading wave of glitter and confetti would shower down upon the mafiosoʼs precious hat and expensive coat.

Then would come the screaming, the creative profanity, the threats of dismemberment, perhaps even a miniature black hole or two warping the hallwayʼs structural integrity. It would be magnificent. It would be hilarious. And most importantly, it would alleviate the crushing boredom that had been eating away at Dazai all evening.

He heard footsteps before he saw their owner, the distinctive click of heeled boots, though slower than usual. More deliberate. The rhythm was wrong, lacking Chuuyaʼs typical aggressive staccato.

Dazai pressed closer to his mirror, breath held. The shadow rounded the corner first, stretching elongated across the floor, and then Chuuya himself appeared. Even at this distance, Dazai could see the weariness carved into every line of his partnerʼs body.

The black coat hung heavier than normal, the hat sat slightly askew, an unprecedented disorder that Chuuya would never tolerate under ordinary circumstances. His gloved hand dragged along the wall as he walked, fingers trailing the paneling as if he needed the support to stay upright.

He looks terrible, Dazai noted with clinical detachment, the observation floating through his mind without sympathy. Well, this should cheer him up. Nothing like a good rage to shake off the misery.

Chuuya reached the door. His hand found the handle. Dazaiʼs grin widened to its maximum extent. The door swung inward.

The bucket tipped with a metallic clang, and the avalanche descended, a shimmering waterfall of iridescent glitter and confetti that seemed to hang in the air for an impossible moment, catching the dim light like a perverse celebration. It struck Chuuya in a wave, coating his hat, his shoulders, his hair, the collar of his coat.

Fine glitter dust billowed outward in a cloud, settling across his face, catching on his eyelashes, drifting down his shirt. For one suspended second, the image was almost beautiful, this small, fierce figure transformed into something sparkly and absurd, like a disgruntled ornament on a discarded Christmas tree.

Dazai pressed his hand over his mouth to stifle the laughter already building in his chest, waiting for the eruption.

It never came. Chuuya stood frozen in the doorway, one hand still on the door handle, glitter drifting down around him like snowfall in a globe. He didnʼt move. Didnʼt swear. Didnʼt even brush the confetti from his hat.

The silence stretched, two seconds, five, ten, and Dazaiʼs grin faltered, its edges softening into confusion. Something was wrong. Something was fundamentally, terribly wrong, and the realization crept through him like ice water.

Then Chuuyaʼs shoulders began to shake, and the smaller man lifted his free hand to his face, pressing the heel of his palm against his eye with a gesture so raw, so un-Chuuya, that Dazai felt something in his chest crack open the way a window does when struck by a stone.

He could see it now, the wetness gathering at the corners of those striking blue eyes, catching the light along with the glitter. The way Chuuyaʼs jaw clenched, fighting a battle it was clearly losing.

The tears spilled over, leaving clean tracks through the sparkling dust on his cheeks. Dazaiʼs hand fell away from his mouth. The laughter died in his throat, strangled before it could take breath, and he rose from his place slowly, as if any sudden movement might shatter something irrevocably.

The silence was deafening, a roar that filled the corridor and drowned out every clever remark, every dismissive joke, every shield he had ever constructed. Chuuya Nakahara was crying, and Dazai Osamu had put those tears there.

For a long moment, Dazai couldnʼt move. He stood in the dim hallway like a man who had stepped out of his own body, watching the scene from some distant vantage point.

His mind, always so quick, so calculating, stalled completely, grinding through useless calculations like a broken machine.

This wasnʼt supposed to happen. This wasnʼt the plan. Chuuya doesnʼt cry.

But the evidence was right in front of him, undeniable and devastating: the slight heave of Chuuyaʼs chest, the futile swipes at his eyes that only spread the glitter further across his face, the broken, shuddering exhale that escaped him.

Dazai had seen Chuuya bleed, had watched him crush men into the earth with a flick of his fingers, had witnessed him bark orders through a hail of gunfire without flinching. He had never seen him like this, stripped down to something small and wounded, standing in a doorway covered in shimmer like a cruel joke the universe had played on them both. And Dazai had set it up.

He had orchestrated this exact moment with the same precision he used for operations that ended in death, and somehow, impossibly, he had miscalculated. Not the bucketʼs position or the doorʼs angle, he had miscalculated Chuuya. The realization sat in his chest like broken glass.

He moved without deciding to, his usual theatrical grace abandoned for something quieter, more careful. His footsteps made no sound as he approached, and when he reached the doorway, he didnʼt speak, didnʼt offer a glib apology or a deflecting quip.

He simply reached out and took Chuuyaʼs wrist, gently but firmly, steering him away from the glitter-strewn threshold and the office beyond. Chuuya flinched at the contact, a sharp sound catching in his throat, half protest, half something more vulnerable, but he didnʼt pull away. He didnʼt curse or shove or activate his ability.

He just let himself be guided, which frightened Dazai more than any explosion of rage ever could. They walked a few doors down to a small, unused sitting room that the executive floor kept for late-night strategy sessions, and Dazai pushed the door open, nudging Chuuya inside before closing it behind them with a soft click that felt enormously final.

The room was dark except for the city glow filtering through the single window, painting pale rectangles across the floor. Dazai guided Chuuya to the leather sofa against the wall and pressed lightly on his shoulder until he sat, hat still glittering, confetti still clinging to the dark fabric of his coat.

Only then did Dazai kneel, bringing himself to Chuuyaʼs level, his brown eyes searching the averted face with an unfamiliar intensity.

“Chuuya,” he said, and his voice came out stripped of its usual lilting irony, just his name, spoken simply, the way one might say something true.

Chuuya didnʼt look at him. His jaw remained clenched, the muscles working beneath skin still dusted with glitter that caught the faint window light like scattered stars.

His gloves came up to his face again, pressing hard against his eyes as if he could shove the tears back through sheer force of will. A shaky breath escaped despite his efforts, and the sound of it, the raw, involuntary quality, made Dazaiʼs hands twitch where they rested on his knees. He had never felt this particular ache before, this strange pressure behind his own ribs that seemed to worsen with every quiet, stifled sound Chuuya made.

It was uncomfortable. It was unfamiliar. And it was entirely his fault.

“Stop—” Chuuyaʼs voice cracked on the word, hoarse and ragged, and he cleared his throat viciously as if he could carve the weakness out of it.

“Donʼt fuckinʼ look at me like that.” But there was no heat in the command, none of the usual fire that made Chuuyaʼs anger feel like standing too close to a bonfire.

This was something ember-low and smoldering, fed by exhaustion and humiliation and the accumulated weight of whatever had gone wrong on that mission. Dazai didnʼt obey. He kept his gaze steady, his expression unguarded in a way it almost never was, letting Chuuya see him clearly, without the mask, without the joke, without the endless performance that usually stood between them like a wall.

Slowly, carefully, Dazai reached for Chuuyaʼs hat. His fingers brushed the brim with a hesitancy that would have been unthinkable an hour ago, when touching the hat was a provocation, a game, a deliberate spark to ignite Chuuyaʼs wrath. Now it was something else entirely, an offering, perhaps, or a question asked with hands instead of words.

Chuuyaʼs shoulder tensed beneath the contact, but again, he didnʼt pull away, didnʼt snap at him, didnʼt do any of the things Dazai had built his entire understanding of their partnership around.

His hands finally dropped from his face, settling limp in his lap, and the full devastation of his expression lay bare in the dim light: the tear tracks cutting through the glitter, the slight tremor in his lower lip that he was biting down on to still, the way his blue eyes couldnʼt seem to find a place to land that wasnʼt Dazaiʼs face.

When the hat lifted away, trailing a shower of glitter onto the floor, the face beneath it looked younger somehow, and more exhausted, orange hair mussed and sticking up at odd angles, blue eyes red-rimmed and still dangerously wet, that fierce expression dulled to something that barely held together.

Dazai set the hat aside and, after a moment of hesitation that felt longer than any calculation he had ever made, raised his hand to brush a stray piece of confetti from Chuuyaʼs cheek. His thumb lingered there, just barely, just enough, and the touch was so gentle it seemed to belong to someone else entirely.

Chuuya flinched at the contact, not away from it, Dazai realized with a strange sting, but into it, almost imperceptibly, like a man starved of warmth who couldnʼt quite bring himself to reach for it directly. The tension in his shoulders didnʼt dissolve, but it shifted, redistributing into something less defensive, more exhausted.

Something twisted in Dazaiʼs chest sharp, unfamiliar, and distinctly unpleasant.

He had imagined seeing Chuuya broken in many contexts over the years, always with a detached clinical interest or a sharp edge of rivalry, but never like this. Never with this strange pressure building behind his own sternum that made him want to say things he didnʼt have words for.

“The mission,” Chuuya started, then stopped. Swallowed.

His voice, when it came again, was barely above a whisper, so quiet that Dazai had to lean in to hear, bringing them closer than they had been in any context that didnʼt involve violence.

“We lost them. All three informants, burned before we could extract anything. And Takeda—” He broke off, and something in his expression fractured further, hairline cracks spreading across the facade.

“Takedaʼs not coming back.” The name meant nothing to Dazai, just another foot soldier, another expendable piece on the board. But it meant something to Chuuya; that much was clear from the way he said it, like the syllables themselves were glass he was chewing on.

Of course. Chuuya had always been stupidly, stubbornly attached to the people under his command, carrying their weight like he carried everything else, on his own shoulders, until the bones cracked.

Three informants lost. A soldier dead. A failed operation. And then, as the final straw, he had walked into his own sanctuary only to be ambushed by his partnerʼs idiotic prank, a bucket of glitter, of all the humiliating, trivial things. No wonder he had broken. The wonder, Dazai thought with growing self-loathing, was that he hadnʼt broken sooner.

“Iʼm sorry.” The words left Dazaiʼs mouth before he could examine them, and they felt foreign on his tongue, clumsy, inadequate, utterly insufficient for the weight they needed to carry.

He couldnʼt remember the last time he had apologized and meant it, had offered those two words without an ulterior motive or a sardonic undertone. But he meant them now, with a sincerity that startled him, and he watched Chuuyaʼs eyes widen fractionally at the sound of it, proof, perhaps, that the apology was as unexpected as the tears.

Without quite deciding to, Dazai shifted forward on his knees and settled carefully beside Chuuya on the sofa, close enough that their shoulders nearly touched. He didnʼt reach for him again, didnʼt try to push further into a space that Chuuya might not want him in, but he stayed there, present, quiet, and inexplicably unwilling to leave.

The glitter still glimmered on Chuuyaʼs coat and in his hair, catching the city light through the window, and Dazai stared at it without speaking, thinking of how a single miscalculation could cascade into something so far beyond his control.

They sat in silence for a long moment, the kind that held too much to break with words.

Chuuyaʼs breathing was uneven, shallow inhales, shaky exhales, the rhythm of a man still fighting a battle against himself, still trying to cage something that had already slipped its restraints.

Dazai found himself counting the breaths, a habit he usually reserved for calculating an enemyʼs stress level or predicting the moment before a target broke under interrogation.

But this wasnʼt interrogation, and Chuuya wasnʼt an enemy, and the counting felt different now, less like strategy and more like the desperate attention of someone trying to memorize a sound theyʼd never heard before and might never hear again.

The silence stretched, thin and fragile, until Dazai felt the compulsion to fill it, not with the noise he usually manufactured, but with something steadier.

He could see the tremor in Chuuyaʼs hands, the way his head continued to dip forward despite his best efforts to keep it up. The gravity user was fighting the exhaustion with the same stubbornness he applied to everything else, a losing battle against a weight far heavier than the laws of physics.

Acting on an instinct that bypassed his usual cynicism, Dazai shifted closer. He reached out, his bandaged hand hovering for a moment before settling gently atop the crown of Chuuyaʼs head. The contact was light, experimental, feeling the heat of Chuuya’s scalp through his hair. When Chuuya didnʼt flinch away, Dazai applied a soft, guiding pressure, easing him downward.

“Come here,” Dazai murmured, his voice barely a rasp in the quiet room. He guided the shorter manʼs head down until it settled heavily onto his lap.

Chuuya offered no resistance, his body finally surrendering to the pull of gravity he was usually so adept at defying.

As his weight settled against Dazai’s thighs, Dazai felt a strange, heavy warmth seep through the fabric of his trousers. Chuuya’s face was turned away, buried slightly against the dark material of Dazai’s coat, effectively hiding any lingering trace of his tears.

The glitter that coated Chuuya’s hair transferred in small, shimmering specks to Dazai’s lap, a galaxy of debris marking the collision of their worlds. For a long moment, the only sound was the uneven, wet rhythm of Chuuyaʼs breathing gradually slowing, the harsh edge of his shock dulling into something more manageable.

Dazai looked down at the sight before him, a formidable mafioso reduced to something fragile and trusting in his lap, and felt an unfamiliar twinge of responsibility settle in his chest. He began to move his hand, his fingers carding through the soft, orange strands. He started with tentative strokes, avoiding the tangles and the remaining confetti, gradually working his way to the back of Chuuyaʼs head.

There was a rhythm to it, a silent, grounding cadence that seemed to communicate what his clumsy words could not. When his fingernails scratched lightly against the scalp, Chuuya let out a tiny, shuddering exhale, his hand unconsciously gripping the fabric of Dazai’s coat as if to anchor himself.

“Rest now, Chuuya,” Dazai whispered, the command soft and absolute, stripping away the thousand masks he usually wore.

He kept the motion of his hand steady, a repetitive, soothing gesture that felt dangerously close to tenderness. In the dim light of the unused office, with the dust motes dancing around them and the city humming a distant lullaby, the bandaged executive remained a statue of stillness, letting his partner find what little shelter he could offer in the wreckage of a terrible day.

The tension bled out of Chuuya in increments, first the rigid set of his shoulders, then the white-knuckled grip on Dazaiʼs coat loosening finger by finger until the hand went slack, and finally the furrow between his brows smoothing into something approaching peace.

His breathing deepened, the shuddering gasps leveling into a slower, steadier rhythm that Dazai could feel against his legs like the tide pulling back from the shore. The tears had stopped, though the evidence of them remained, the salt tracks dried on glitter-dusted cheeks, the faint redness that rimmed his eyes, the damp spot where his face had pressed into Dazaiʼs coat. Dazai didn't remark on any of it.

He simply continued his ministrations, fingers working through Chuuyaʼs hair with a patience that would have been unrecognizable to anyone who knew him only as the sadistic prodigy of the Port Mafia. Occasionally his thumb would trace a small circle at Chuuya's temple, or his nails would drag gently through the hair at the nape of his neck, and each small motion earned him another increment of relaxation, another tiny surrender from a man who never surrendered to anything.

The corridor outside remained silent, the headquarters holding its breath as if sensing the fragility of the moment. Dazai found himself cataloging details he would normally disregard, the faint scent of gunpowder and expensive cologne clinging to Chuuyaʼs coat, the way a single piece of gold glitter had adhered to the curve of his ear, the subtle flutter of his eyelashes as exhaustion finally dragged him under.

It was strange, Dazai thought, how the absence of something could be so loud. The absence of Chuuyaʼs voice raised in fury, the absence of his fists swinging, the absence of all the familiar violence that usually defined their interactions. In their place was this, quiet, warmth, the weight of a head in his lap and the unsettling realization that he did not hate it. He did not hate it at all.

His hand did not stop its motion, even as Chuuyaʼs breathing evened out completely and his body went heavy with sleep. If anything, the strokes grew slower, more deliberate, as if Dazai was trying to memorize the texture of this moment through touch alone.

His mind, ever restless, circled back to the image of Chuuya standing in that doorway, glitter raining down around him while tears tracked silently down his face. The memory lodged itself somewhere deep and uncomfortable, a wound he could not bandage or ignore.

He had wanted a reaction, any reaction, to break the monotony of another empty night. What he had gotten instead was a glimpse behind a door he had never thought to look for, let alone open. And the question that now gnawed at him, persistent and unwelcome, was how long Chuuya had been standing at that breaking point before Dazaiʼs stupid, thoughtless prank had finally pushed him over the edge.

The city lights shifted through the window as the night deepened, painting new patterns across the floor and over the two figures on the sofa.

Dazai knew he should move, should slip out from under Chuuya, retrieve his hat, maybe even clean up the mess in the office before the morning shift arrived and started asking questions.

He knew, with the same calculating precision he applied to everything, that staying like this served no strategic purpose, advanced no scheme, offered him no advantage. But he stayed. His hand continued its gentle path through orange hair, his gaze remained fixed on the quiet rise and fall of Chuuyaʼs chest, and for once in his life, Dazai did not calculate his next move.

He simply remained, a steady presence in the dark, holding space for a partner who had never asked him to, and probably never would. But that was alright.

Some things, he was beginning to understand, did not need to be asked for to be given.
