The Stranger in My Brother's Skin

Osamu noticed the skirt first. Too short, even for their school's loosened dress code—a slash of red plaid that barely cleared Atsumu's thighs. Then the makeup. Thick, cakey, dark lipstick smeared like a wound across his brother's mouth.

This wasn't a slow slide. It was a drop off a cliff.

A week ago, Atsumu wore the standard uniform—top button undone, sleeves rolled up, testing the limits. He was obnoxious, loud, arrogant, but he was still Atsumu. Now some stranger had crawled into his skin.

"Mornin', Samu," Atsumu chirped, sliding into his desk with an exaggerated flick of his bleached-blond hair. New color too. Harsh, brassy yellow, like he'd done it in a bathroom mirror with a grudge. Smelled like cheap perfume and cigarettes.

Osamu grunted, stared at his bento. He'd started bringing lunch from home to avoid the cafeteria line, avoid watching Atsumu parade around like a sideshow act.

"Not gonna say anythin'?" Atsumu leaned forward, elbows on Osamu's desk, crowding him. Voice too bright, brittle as thin ice. "I think the hair looks good. Makes me stand out."

"Ya always stood out." Osamu kept his eyes down. "Didn't need to look like a clown for it."

Atsumu's smile flickered—just a fraction of a second—then snapped back. "Jelous 'cause yer stuck with that boring brown? Don't worry, Samu. Not everyone can pull off this level of style."

He laughed. Sharp, hollow. Then sauntered away to his seat on the other side of the classroom. Osamu watched him go. The clack of heels on tile. Heels. Atsumu was wearing heels. Straps wound around his ankles, showing off the sharp bones.

What the hell happened to you?

The question burned in his throat. He swallowed it. Didn't want to know. Didn't want to give Atsumu the satisfaction of caring.

The routine kept going.

Atsumu cycled through the student body like a virus. Monday—a second-year from the soccer team, lanky with kind eyes, looking at Atsumu like he was precious. Wednesday—Atsumu draped over a third-year from drama club, arm around her waist, his hand in her back pocket. Friday—someone behind the gym. Osamu didn't catch the face. Didn't want to.

Between conquests, Atsumu was cruel.

He mocked a first-year girl for her acne until she cried. Spread a rumor about a classmate's family—no basis in truth. Laughed when someone tripped in the hallway. Not the old, infectious laugh that used to echo through their shared bedroom. A cold, ugly sound that made people flinch.

But never, not once, was he cruel to Osamu.

That was the strangest part. Atsumu stayed bizarrely, almost desperately soft toward his twin. Saved him the last onigiri from the convenience store. Left notes in Osamu's locker with little doodles of them as onigiri—one grumpy, one sharp-toothed grin. Still called him "Samu" in the same old way, a lifeline thrown across the widening gap between them.

It made Osamu's skin crawl.

Not the notes. Not the onigiri. The disconnect. How could Atsumu be a monster to everyone else and still tuck a blanket around Osamu's shoulders when he fell asleep studying? How could he kiss strangers and still save him a seat at lunch?

It was wrong. Twisted. Atsumu kept him in a glass case, a perfect brother for him alone, while shattering everything else.

Osamu started avoiding him.

Ate lunch with Suna—the tall, perpetually bored middle blocker who saw through people. Walked to class through the far stairwell. Stayed late in the gym, practicing serves until his shoulders ached, so by the time he got home, Atsumu would already be behind a closed door.

Cowardly. He knew it. But the alternative—confronting Atsumu's new face, the mask of makeup and malice—felt impossible.

Thursday. The dam finally broke.

Atsumu appeared at his desk during lunch break, tray in hand. Pink crop top showing a strip of pale stomach. Skirt so short it was practically a belt. Lipstick fresh, glossy red, like he was already bleeding.

"Hey, Samu," he said, voice almost normal. Almost the old Atsumu. "Wanna eat together? I got those shrimp crackers ya like."

Osamu didn't look up. Rearranged rice in his bento box, pushed the umeboshi plum to the side like it'd personally offended him. "I'm eatin' with Suna."

"Oh." Pause. Atsumu shifted, heels clicking. "Okay. I'll join ya."

"No."

Flat. Hard. Osamu finally looked up, saw Atsumu's face—the careful makeup, false brightness—and something inside him snapped.

"I just don't want to eat with you." The words tasted like ash. "Go find one of yer other... friends."

Atsumu's smile didn't break. It cracked. A hairline fracture spreading from the corner of his lips to the hollow of his cheek. His eyes, rimmed with dark liner, glistened.

For a terrible, suspended moment, Osamu thought he'd cry.

Then Atsumu laughed. Small, broken sound. "Your loss."

He turned and walked away, hips swaying with forced confidence. Dropped his tray on a table across the cafeteria. Sat down next to a boy from the basketball team. Laughing again within seconds. Loud. Brassy. Fake.

Osamu watched a single tear catch the light on Atsumu's cheek before he wiped it away with the back of his hand, smearing black liner across his skin.

Good, a cruel voice whispered in his head. Maybe now he'll stop.

But guilt coiled in his stomach. Cold, greasy snake.

Suna slid into the seat across from him, silent as a cat, unpacked his lunch without a word. He always knew when not to speak. For a while, they ate in quiet. Osamu pushed his food around. Suna chewed his cucumber sandwich with methodical precision.

"You're a shitty brother," Suna said finally.

Osamu's chopsticks stopped. "What?"

"You heard me." Suna's gaze was flat, unreadable. "I'm not sayin' you're wrong to be worried. But that—what you just did—that wasn't worry. That was cruelty."

"He's the one actin' like a—"

"Like a what? A teenager makin' bad choices? A person who's clearly strugglin'?" Suna's voice stayed level, but there was an edge. "You're his twin. His other half. If you won't look out for him, who will?"

Osamu opened his mouth to argue, but Suna was already standing, gathering his tray.

"Finish your lunch. We have class in ten."

He walked away, leaving Osamu alone with cold rice and colder truth.

They were halfway back to the classroom when they heard it.

A rhythmic sound. Soft. Wet. Coming from the empty storage classroom at the end of the hall. Door slightly ajar, a sliver of light spilling into the dim corridor.

Suna stopped. Osamu stopped too, heart sinking.

"Don't," Suna said, but Osamu was already moving, drawn by something sick and curious.

He peered through the gap.

Atsumu pressed against the teacher's desk, skirt hiked up around his waist, shirt unbuttoned. A senior—former volleyball team captain, someone Atsumu always looked up to—had him pinned, mouth on his neck, hands roaming.

Atsumu's head was thrown back, eyes closed. Lips parted. He didn't look like he was enjoying it. He looked like he was somewhere else entirely. A doll being posed.

Osamu's stomach lurched.

"Disgustin'," he muttered, stepping back. "He'll give his body to anyone."

The slap came so fast he didn't see it coming. His head snapped to the side, cheek stinging. He stared at Suna, shocked.

Suna's hand was still raised, his face twisted into something Osamu had never seen—anger. Real, burning anger.

"Aren't you worried?" Suna's voice was barely a whisper, but it cut like a blade. "He's still your twin. Your brother. And all you can say is 'disgusting'?"

Osamu touched his cheek. "He—"

"He's dyin', Osamu. Right in front of you. And you're too busy bein' embarrassed to see it."

Suna turned and walked away, footsteps steady and final. Osamu stood frozen in the hallway, the sounds from behind the door washing over him, a horrible soundtrack he couldn't escape.

That night, the house was silent.

Parents working late, as usual. Fridge humming. Microwave clock blinking 11:47 PM. Osamu sat on the living room couch, textbook open in his lap, words meaningless shapes.

Couldn't stop thinking about Atsumu's face. The crack in the smile. The tear. The way he'd looked in that classroom—empty, hollow, a shell wearing his brother's skin.

He's dyin'. Right in front of you.

Suna's words echoed in his skull.

Upstairs, a door opened. Soft footsteps padded down the hall. Bathroom door clicked shut. Water ran for a moment, then stopped.

Osamu waited.

House too quiet. Should go up. Should check on him. Should apologize.

But he was tired. Tired of the drama, the clothes, the cruelty. Tired of watching his brother self-destruct. Tired of caring.

He closed his eyes.

Then he heard it.

A muffled sob. Followed by a thump.

Osamu's eyes snapped open. Heart lurched. He was on his feet before he knew he'd moved, taking the stairs two at a time, textbook abandoned on the couch.

"Atsumu?"

No answer.

Bathroom door closed. Light seeping from under the crack, thin yellow line. Osamu knocked, knuckles hard against the wood.

"Oi. Atsumu. Open up."

Silence.

Strange, cold dread slithered down his spine. He pressed his ear to the door. Heard breathing—ragged, uneven—and something else. Drip. Drip. Drip.

"Atsumu, I swear to god, open the damn door."

Nothing.

Hands shaking, he tried the knob. Locked.

Slammed his shoulder against the door. Once. Twice. Wood groaned but held. Third try, the frame cracked, and he tumbled through.

The sight that greeted him stopped time.

Atsumu slumped against the bathtub, back against the porcelain, legs splayed. Still in the crop top and skirt from school, but the skirt was soaked, dark red spreading across the plaid like a blooming flower. His wrists laid open—clean, precise cuts that gaped like mouths. A razor blade glinting on the floor beside him.

Pills scattered across the tile. Orange and white, a constellation. Some crushed, some whole. Empty bottle of their mother's sleeping pills on its side.

Atsumu's eyes half-open, glassy, unfocused. Lips moving, words so quiet Osamu had to lean in to hear.

"Let me go," Atsumu whispered. "I'm so tired."

Blood pooling. Dark. Too much. Creeping across the white tile, reaching for Osamu's shoes.

For one horrible, paralyzing second, Osamu couldn't move. Brain refusing to process the image in front of him—his brother, his other half, bleeding out on the bathroom floor.

Then the world snapped back into focus, and he was moving.

"ATSUTMU!"

He dropped to his knees, hands flying to Atsumu's wrists. Blood warm, slick, pumping out in a rhythm that was already slowing. Pressed down, hard, with both hands, feeling the torn edges of skin beneath his fingers.

Atsumu didn't even flinch.

"No, no, no, no, no." Osamu's voice cracked, high and desperate. "Stay with me. Stay with me."

Fumbled for his phone with one hand, other still pressing down on the wound, palm sticky with his brother's life. Dialed with his thumb, smearing blood across the screen.

"Emergency services, what's your emergency?"

"My brother," Osamu choked out. "He—he cut his wrists. He took pills. He's not—he's not movin'. Please, please, I need an ambulance, I need—" His voice broke into a sob. "Please hurry."

"Sir, I need you to stay calm. Is he breathing?"

Osamu looked at Atsumu's chest. Rising. Barely. Shallow, uneven breaths.

"Yeah. Barely."

"Keep pressure on the wounds. Help is on the way. Don't hang up."

Osamu didn't. Held the phone between his ear and shoulder, both hands pressed to Atsumu's wrists, blood seeping through his fingers. Stared at his brother's face—pale, slack, makeup smeared into a grotesque mask. Blond hair dark at the roots, damp with sweat.

"Why?" Osamu whispered, voice raw. "Why didn't ya tell me?"

Atsumu's eyelids fluttered. For a moment, his gaze seemed to focus, find Osamu's face. His lips moved.

"Samu…"

"I'm here." Osamu's tears fell freely now, dropping onto Atsumu's cheeks, mingling with the smeared makeup. "I'm here, okay? Don't leave. Don't you dare leave me."

Atsumu's lips curved into the ghost of a smile. His eyes slid closed.

"No, no, no—Atsumu!"

Sirens wailed in the distance.

The next few hours were a blur of fluorescent lights, gurneys, doctors' voices that faded in and out like a bad radio signal. Osamu sat in a plastic chair in a hospital waiting room, hands still stained red, blood drying into brown flakes under his fingernails.

Suna arrived at some point. Didn't say anything. Just sat down next to Osamu and waited.

The doctor came out after what felt like an eternity. Face tired, but not grim. "He's stable. We pumped his stomach and closed the wounds. He lost a lot of blood, but he's young and healthy. He'll need a psychiatric evaluation, but physically, he should recover."

Osamu's head dropped forward, a sob wrenching out of his chest. "Can I see him?"

"He's asking for you."

The room was dim, blinds drawn against the morning sun. Atsumu looked small in the hospital bed, drowning in white sheets. Wrists bandaged, thick white gauze peeking out from under the sleeves of his gown. Face clean—makeup scrubbed away—and without it, he looked young. Vulnerable. Like the boy who used to climb into Osamu's bed during thunderstorms, claiming he was scared of the dark.

He turned his head when Osamu entered. Eyes red, swollen, but clear.

"Samu."

Osamu crossed the room on shaky legs. Sank into the chair beside the bed, reached out, and took Atsumu's hand—carefully, gently, avoiding the bandages.

"I'm sorry," Osamu whispered. "I'm so sorry."

Atsumu's face crumpled. Tears spilled down his cheeks, silent and endless. "Ya hate me."

"No." Osamu shook his head, his own tears falling freely. "No, I don't hate ya. I was scared. I was—I was disgusted, but not with ya. With myself. For not seein'. For not askin'. For pushin' ya away when ya needed me."

Atsumu let out a shaky breath. "I didn't know how to say it. I didn't—I couldn't—I thought if I made myself loud enough, bright enough, someone would see me. But no one did. No one but ya, and then ya looked away too."

Osamu's grip tightened. "I won't look away again. I swear it."

"I was so lonely, Samu." Atsumu's voice broke, the words tumbling out like water through a cracked dam. "I felt like I was drownin' every day, and everyone just watched. I thought if I was mean enough, they'd hate me, and that would be easier. But it wasn't. It just made it worse. And I—I couldn't stop. I couldn't stop the spiral. The only time I felt anythin' was when I was with someone else, but even then, I felt nothin'. I felt nothin'."

"I should've been there." Osamu pressed his forehead to their joined hands. "I should've noticed. I was so busy bein' embarrassed, so busy hating the way ya acted, that I didn't stop to ask why. I'm a shitty brother."

"No." Atsumu squeezed his hand weakly. "Ya were hurtin' too. I saw it. I just didn't know how to stop."

They sat in silence for a long moment, the steady beep of the heart monitor the only sound. Osamu lifted his head and looked at Atsumu—really looked. Dark circles under his eyes. Gaunt hollows of his cheeks. Fragile set of his shoulders.

"We're gonna get through this," Osamu said. "Together. I'm not leavin' ya again, Atsumu. No matter what."

Atsumu let out a wet laugh. "Even when I wear stupid skirts?"

"Especially when ya wear stupid skirts. But we're talkin' about that too. And seein' a counselor. And maybe—maybe callin' mom and dad."

Atsumu winced. "They're gonna be so mad."

"They're gonna be scared," Osamu corrected. "Like me. But they'll get over it. We all will."

Atsumu looked at their hands, his thumb tracing small circles on Osamu's knuckles. "Samu?"

"Yeah?"

"I don't wanna die."

The words hung in the air, heavy and raw.

"Good," Osamu said, voice thick. "Because I don't think I could survive without ya."

Atsumu smiled. Small, fragile, edges still raw and bleeding. But it was real. For the first time in weeks, it was real.

Outside the window, the sun was rising, painting the sky in shades of pink and gold. A new day. A new start.

Still a long way to go. Hard conversations, therapy sessions, setbacks. Atsumu wouldn't heal overnight, and neither would their relationship. The scars on his wrists would fade but never disappear—a permanent reminder of how close they'd come to losing everything.

But in this moment, holding his brother's hand, Osamu felt something he hadn't felt in weeks: hope.

"I love ya, Samu," Atsumu whispered, eyes already drooping with exhaustion.

"I love ya too, you reckless idiot." Osamu squeezed his hand. "Now sleep. I'll be here when ya wake up."

Atsumu's eyes slid closed, his grip loosening as sleep pulled him under. But his hand stayed in Osamu's, warm and alive, and that was enough.

Osamu leaned back in the chair, still holding on, and watched the sunrise paint his brother's face in gold.

They were broken. They were healing.

They would make it.
