The Armor of Lip Gloss

The first time Atsumu Miya walked into Inarizaki High wearing a skirt, the whole building forgot how to breathe.

Not just because of the skirt—though that alone would've been enough to shatter the social order of a volleyball powerhouse. It was everything. His hair, bleached to near-white gold, swept back like he'd spent an hour getting it exactly right. The heavy eyeliner, smudged at the edges like he'd been crying, but his eyes were dry and sharp as broken glass. Lip gloss catching the fluorescent lights. Heels, black and vicious, adding three inches to his height and turning his walk into a deliberate, hip-rolling performance.

He looked like a punk rock fever dream. He looked like a threat.

Whispers trailed behind him. Students pressed themselves against lockers to let him pass, eyes wide, phones already buzzing. Atsumu ignored them all—chin up, gaze straight ahead, mouth set in a line that promised violence if anyone dared.

Osamu watched from the end of the hallway, his rice ball forgotten in his hand.

He'd known something was wrong for weeks. Months, maybe. The signs were there—breadcrumbs through a dark forest—but Osamu had been too busy, too angry, too disgusted to follow them. Atsumu started coming home later. Stopped eating dinner with the family. Locked his bedroom door, a habit so foreign their mother knocked for three days straight before giving up.

The first hint was the makeup. Atsumu had always been vain, but this was different. Armor, painted on with an unsteady hand. Then the clothes shifted—from sporty to tight to revealing in a slow, unsettling slide. And two weeks ago, Atsumu stopped speaking to him entirely.

Not fighting. Not ignoring with attitude. Just... nothing. Empty eyes sliding past Osamu like he was made of glass.

Now this.

"Atsumu." Osamu's voice came out flat. Nothing behind it.

Atsumu paused, one hand on the classroom doorframe. He turned, slow and deliberate, and Osamu felt the full weight of his brother's new persona hit him like a physical blow. The makeup was flawless—contouring a face that had always been beautiful into something harder, sharper. The skirt was plaid, short, showing off legs that had spent years jumping for spikes. The heels changed his posture—weight shifted forward, shoulders squared like he was ready for a fight.

"Samu." Even his voice had changed. Lower, drawling, laced with mockery that made Osamu's teeth clench. "Like the new look?"

"You look ridiculous."

The words came out before Osamu could stop them. Something flickered in Atsumu's eyes—quick, there and gone, like a fish breaking the surface of dark water. Pain, maybe. Hurt. Then it was replaced by ice, and Atsumu laughed.

"Jealous? I know you could never pull this off. Too ugly."

Students were watching. Phones were recording. Heat crept up Osamu's neck—the familiar anger that had been living in his chest for weeks surging forward. He wanted to grab Atsumu by the collar, shake him until whatever demon had possessed him fell out. Wanted to scream.

Instead, he turned and walked away.

---

The days that followed were a masterclass in destruction.

Atsumu threw himself into his new identity with a dedication that bordered on psychotic. Shorter skirts, higher heels, brighter makeup. He draped himself over boys and girls alike, kissing them in the hallways, touching them with a casual ownership that made Osamu's stomach turn. Changed partners like other people changed socks—every day a new name, a new body pressed against his in corners where teachers didn't look.

And he was cruel. God, he was cruel.

Osamu watched from across the cafeteria as Atsumu laughed in a girl's face, loud and mocking, before walking away. The girl's eyes were wet, her hands shaking. Atsumu didn't look back.

"Atsumu-senpai said I was boring," the girl whispered to her friend, loud enough for the whole room to hear. "He said I wasn't worth his time."

The friend's arm wrapped around her, pulling her close. Atsumu's voice echoed through the cafeteria: "Maybe if you weren't so desperate, people would actually wanna talk to ya."

The cruelest things always came in that drawling, almost playful tone. Atsumu had always been sharp-tongued—they both had, products of a competitive household where words were weapons and the first one to flinch lost. But this was different. Calculated. Surgical.

Osamu stopped eating lunch with him. Then he stopped sitting near him. Then he started leaving the room whenever Atsumu entered.

He told himself it was disgust. Atsumu had become everything they'd both been taught to despise: shallow, cruel, attention-seeking. He'd abandoned the volleyball team—walked out mid-practice without a word, leaving Kita staring after him with an expression Osamu couldn't read. He'd abandoned their friendship, their brotherhood, the bond that had defined them since birth. He'd become a stranger wearing Atsumu's face.

So Osamu let him go.

---

"You need to stop avoiding him." Suna's voice cut through the silence of the gym, where Osamu was supposed to be practicing but was instead sitting on the floor, staring at nothing.

"I'm not avoiding him. I'm just not seeking him out."

"That's avoidance." Suna sat down beside him, long legs folding gracefully. His expression was unreadable, but there was something in his voice Osamu didn't like. Sharp. "He's your twin, Osamu."

"I know what he is."

"Do you?"

Osamu turned to look at him. Suna's dark eyes were fixed on the opposite wall, but his jaw was tight. "What's that supposed to mean?"

"It means you're being willfully blind." Suna's voice was quiet, measured, but steel underneath. "Atsumu doesn't wake up one day and decide to become a completely different person for no reason. Something happened. And instead of asking what, you're letting him drown."

"Drown?" Osamu laughed—the sound ugly even to his own ears. "Have you seen him? He's having the time of his life. New partner every day, everyone's eyes on him, getting exactly the attention he's always wanted."

"Attention." Suna repeated the word like it tasted bad. "Is that what you think this is?"

"What else would it be?"

Suna was quiet for a long moment. When he spoke again, his voice was barely above a whisper. "You know what I see when I look at him? Someone who's running. Someone who's so scared of whatever's inside his own head that he'll do anything to escape it, even if that means destroying himself in the process."

Osamu's chest tightened. He wanted to argue, to dismiss Suna's words as melodrama, but they stuck in his throat like thorns.

"Have you asked him?" Suna continued. "Have you actually tried to talk to him, not as an enemy, but as a brother?"

"No." The word came out harder than Osamu intended. "He made it clear he doesn't want me around."

"Did he, or did you assume?"

The question hung in the air between them, unanswered and heavy. Osamu wanted to be angry, wanted to tell Suna to mind his own business, but the words wouldn't come. Because Suna was right, and Osamu hated him for it.

He hadn't asked. He'd assumed. He'd let his disgust become a wall, and he'd been content to stand on the other side, watching Atsumu destroy himself from a safe distance.

"When did you become the moral compass?" Osamu finally muttered.

"Someone had to." Suna stood, brushing off his uniform. "Because you sure as hell weren't going to."

---

The afternoon was gray and cold when Osamu and Suna decided to cut out of practice early.

Osamu's head wasn't in the game. His sets were sloppy, his footwork wrong, his mind a thousand miles away, following a trail of blonde hair and short skirts through the dark corridors of his imagination. Kita had dismissed him with a pointed look and a quiet "figure it out." Suna followed without being asked.

They took the long way to the locker rooms, through the older wing of the school where the classrooms were unused and the halls dim. The building settled around them, creaking and sighing. Silence thick enough to taste.

That's when they heard it.

A rhythmic sound, muffled by walls and distance but unmistakable. A voice—high, desperate, hitting notes Osamu had never heard from a human throat. A low, harsh grunt in response. The slap of skin against skin.

Osamu's feet stopped moving. His blood turned to ice.

He knew that voice.

"No," he heard himself say, but the word was hollow, meaningless. Suna was already moving, footsteps quick and purposeful as he followed the sound to its source. An empty classroom. The door slightly ajar, a sliver of light spilling into the dark hallway.

Through that sliver, Osamu saw everything.

Atsumu bent over a desk, his skirt hiked up around his waist, makeup smeared across his face. His hands gripping the edges of the wood so hard his knuckles were white. And behind him, moving with a rhythm that made Osamu's stomach lurch—a man. A teacher. Osamu recognized him vaguely—chemistry, young, always smiling too wide and standing too close to students.

The man's hand was in Atsumu's hair, yanking his head back, and Atsumu's eyes were open, staring at nothing, empty as a doll's.

"Tsumu—" The name escaped Osamu's lips before he could stop it, a ghost of the brother he used to know.

Atsumu's head turned. His eyes met Osamu's through the gap in the door.

And then he smiled.

It was the worst thing Osamu had ever seen. A smile with no joy in it, no recognition, no humanity. A mask painted on over something broken and bleeding.

"Enjoying the show, Samu?" Atsumu's voice was light, teasing, even as the teacher behind him grunted and thrust. "Didn't know you were into this kinda thing."

Something inside Osamu snapped.

He laughed.

A terrible, broken sound, ripped from somewhere deep in his chest. He laughed because he didn't know what else to do. Because if he stopped laughing, he might have to acknowledge what he was seeing. Might have to feel it. Might have to understand that his twin brother, the other half of his soul, was being used like a thing, and instead of saving him, Osamu had been avoiding him, abandoning him, leaving him to rot in the hands of a monster.

"Putain de merde," Osamu muttered, the French curse slipping out the way his mother's always did when she was furious. He turned away, still laughing, and walked down the hall.

The slap came out of nowhere.

Suna's hand connected with Osamu's cheek with a crack that echoed through the empty corridor. Osamu staggered, more from shock than pain, his hand rising to his stinging face.

"Shut up." Suna's voice was shaking. His eyes were wet. "Shut the hell up, Osamu."

"What—"

"He's a minor." Suna's voice cracked. "Atsumu is a minor, and that is a teacher, and you're laughing. You're laughing, Osamu. Do you hear yourself? Something is wrong. Something is so deeply, horribly wrong, and you're standing here laughing while your brother is—"

Suna couldn't finish the sentence. He turned away, his shoulders heaving, and pressed his palm against the wall as if he needed it to stay upright.

Osamu's laughter died in his throat.

Silence rushed in to fill the void, cold and accusing. He looked back at the classroom door. It was closed now. The sounds had stopped. He didn't know if that was better or worse.

"I didn't—" he started.

"Save it." Suna's voice was flat. Dead. "You need to go home. Talk to him. Find out what's happening before it's too late."

"He won't talk to me."

"Then make him." Suna turned, eyes red-rimmed but fierce. "Break down his door. Scream at him. Hold him down if you have to. I don't care how you do it, Osamu. Just don't let him disappear. Because from where I'm standing, he's already halfway gone."

---

Osamu didn't go home.

He told himself he needed time to think. To process what he'd seen. He went to a convenience store and bought a rice ball he didn't eat, sat on a park bench until the sky went dark, watched couples and families and runners pass by while his phone sat in his pocket, silent and dead.

He thought about calling. Texting. Walking home and finding Atsumu in their shared room and forcing him to talk—the way they used to when they were kids and the world was small and safe.

But every time he tried to move, he saw that smile. Empty. Hollow. A mask that had become a face.

And he was afraid of what he'd find if he looked behind it.

So he stayed. And waited. Hours slipped away like water through his fingers.

It was nearly midnight when he finally unlocked the front door.

Lights off. House silent—the kind of silence that felt thick and wrong, like the air before a storm. Their parents were away for the weekend, visiting their grandmother in Osaka. They'd asked if the twins would be okay alone.

Osamu had said yes without hesitating.

He kicked off his shoes and padded down the hall toward their shared room. The door was closed. A sliver of light bled from underneath. He paused, hand hovering over the handle, and listened.

Nothing.

No music. No TV. No sound of Atsumu's voice, talking on the phone or singing along or muttering to himself the way he always did when he thought no one was listening.

Just silence.

"Suna was right," Osamu muttered to himself, and pushed open the door.

At first, he didn't understand what he was seeing.

The room was dark except for the lamp on Atsumu's desk. Clothes scattered everywhere—skirts and shirts and the torn remains of what looked like a school uniform. The Atsumu Osamu knew would never have left such a mess. The Atsumu Osamu knew was fastidious, almost obsessive about order.

And there, in the middle of the chaos, was his brother.

Atsumu lying on the floor, curled on his side, blonde hair spread around his head like a halo. Wearing a white shirt, unbuttoned, and nothing else. Face slack, peaceful, makeup washed off, revealing the soft features underneath.

For one beautiful, terrible second, Osamu thought he was sleeping.

Then he saw the blood.

Everywhere. Pooling under Atsumu's arms, spreading across the wooden floor in dark, glistening rivers. The razor blade lay a few inches from his hand, still wet. Empty pill bottles scattered like fallen soldiers around his body.

"Tsumu."

The name came out as a whisper. A prayer. A denial.

Atsumu didn't move.

"Tsumu!" Osamu was on his knees beside his brother, hands finding Atsumu's shoulders, shaking him with a violence born of pure terror. Atsumu's head lolled. His skin was cold. Lips blue.

"No, no, no, no—"

The cuts on Atsumu's arms were deep, purposeful, running from wrist to elbow in parallel lines that looked almost artistic in their precision. Osamu's hands came away red, and he screamed—a raw, animal sound that tore out of his throat and shattered the silence of the house.

He grabbed his phone. Fingers slippery with blood, dropped it twice before managing to dial 119. The operator's voice was calm, practiced, asking questions Osamu couldn't process. Address. Age. What happened.

"My brother," Osamu choked out. "He—he hurt himself. There's so much blood. Please, please send someone, please—"

"Stay on the line with me, sir. Is he breathing?"

Osamu pressed his ear to Atsumu's chest. Heartbeat—faint and thready, but there. "Yes. Barely."

"Good. I need you to put pressure on his wounds. Do you have clean cloths?"

Osamu ripped off his shirt, bundled it, pressed it against Atsumu's arms. The blood soaked through immediately, warm and horrible. Atsumu's face white as paper, lips moving slightly, forming words Osamu couldn't hear.

"Don't you dare die," Osamu hissed, voice breaking. "Don't you fucking dare, Atsumu. I swear to God, I will kill you myself if you—just hold on. Please. Please."

Tears streaming down his face—hot, desperate. He didn't remember the last time he'd cried. Didn't remember the last time he'd felt anything other than anger and disgust and a cold, distant hatred he'd mistaken for righteousness.

"Tsumu, I'm sorry. I'm so sorry. I should have been there. I should have—"

Atsumu's eyes fluttered open.

Unfocused, glassy, drifting across Osamu's face without recognition. For a moment, Osamu thought he was gone—brain already shutting down, watching his brother die.

But then Atsumu's lips moved, and Osamu heard the word, barely audible, carried on a breath that smelled of pills and despair.

"Samu?"

"I'm here." Osamu's voice cracked. "I'm here, Tsumu. I'm not going anywhere. Just hold on. Please. Please hold on."

Atsumu's hand moved—weak, trembling—reaching up toward Osamu's face. Fingers brushed his cheek, leaving a trail of red.

"Didn't think you'd come," Atsumu whispered. "Thought you hated me."

"I don't hate you. I could never hate you." Osamu grabbed his brother's hand, pressing it against his own chest. "I'm sorry. I'm so sorry. I should have asked. I should have seen. I was so blind, Tsumu—so fucking blind."

Atsumu's eyes were closing again, grip loosening.

"Stay awake," Osamu begged. "Please, stay awake. The ambulance is coming. Just stay with me."

"Tired," Atsumu murmured. "So tired, Samu."

"I know. I know you are. But you can't give up. Not now. Not when I finally understand." Osamu pressed his forehead against Atsumu's—feeling the feverish heat of his skin, the shallow flutter of his breath. "I'm sorry I abandoned you. I'm sorry I looked away. I'm sorry I let you believe you were alone. But you're not. You have me. You'll always have me."

"Promise?" Barely a breath.

"Promise."

Sirens getting closer. Red and blue lights flickered through the window, painting the room in urgent, pulsing colors. Footsteps, voices, the crash of the front door being kicked open.

But Osamu didn't look away from Atsumu's face.

Not anymore.

---

The hospital smelled like antiseptic and fear.

Osamu sat in a plastic chair, hands still stained with Atsumu's blood, watching the clock on the wall tick forward in agonizing increments. They'd taken Atsumu away on a stretcher—mask over his face, IV in his arm, tubes and wires and beeping machines surrounding him like a technological cocoon. The doctors had asked questions Osamu couldn't answer. Had he taken pills? How many? How long ago? Osamu shook his head, useless and mute, until Suna appeared beside him—calm, collected, answering everything with a clarity Osamu couldn't muster.

Suna was still there, two chairs away, his phone in his hand. He'd called their parents. Called the school. Called the police—filing a report about what they'd seen in the classroom.

Osamu had done nothing but sit and wait.

"The teacher's been arrested," Suna said, voice quiet in the sterile silence. "They found evidence. Other students. It's been going on for years."

Osamu's stomach turned. "Atsumu—"

"He's a victim. Not a perpetrator." Suna's voice was firm. "You need to remember that, Osamu. No matter what he says, no matter how he acts—he's not to blame for any of this."

"I know."

"Do you? Because the way you've been treating him—"

"I said I know." Osamu's voice cracked. "I know, okay? I know I failed him. I know I was a terrible brother. I know I let my disgust blind me to what was right in front of my face. I know."

Suna was quiet for a long moment. Then he reached over and put his hand on Osamu's shoulder.

"He'll need you," Suna said. "When he wakes up. He'll need you to be there—really there, not the version of you that's been avoiding him for weeks. Can you do that?"

"I can." Osamu looked at his hands, red and raw. "I will. I swear it."

The door to the ICU opened, and a doctor stepped out. She looked tired, but not grim, and Osamu felt a spark of something that might have been hope.

"Miya-san?"

He stood, legs shaking. "Is he—"

"He's stable. We pumped his stomach and stitched his wounds. He's going to be okay." She paused, expression softening. "He's asking for you. He's been asking for you since he woke up."

Osamu didn't remember walking to the room. Didn't remember pushing open the door. He only remembered the sight of Atsumu in the hospital bed—small and pale against the white sheets, arms wrapped in bandages, hair dull and flat against the pillow.

He looked like a child. Like the boy Osamu had grown up with, before everything fell apart.

"Tsumu."

Atsumu turned his head. Eyes red-rimmed, face swollen from crying, and he looked terrified. Not the fake terror of performance—real fear, raw and vulnerable and horrible to witness.

"Samu." His voice was a rasp. "I'm sorry. I'm so sorry. I didn't mean to—I just couldn't—"

"Stop." Osamu crossed the room in three steps and sank onto the bed beside his brother, pulling him into his arms. Atsumu was stiff at first, then melted—face pressed into Osamu's shoulder, body shaking with sobs.

"I couldn't take it anymore," Atsumu whispered. "He told me I was special. He told me I was the only one who understood him. And I believed him, Samu. I believed everything. Because I was so desperate for someone to see me—to really see me—and he pretended to, and I let him do—I let him do everything—"

"Shh." Osamu held him tighter. "It's not your fault. None of this is your fault."

"But I was so mean to everyone. To you. I pushed you away because I was ashamed, and I thought if I made you hate me, I wouldn't have to see the disappointment in your eyes when you found out what I'd become."

"I'm not disappointed." Osamu pulled back, cupping Atsumu's face in his hands, forcing his brother to meet his eyes. "I'm angry. Not at you—at him. At myself, for not seeing. For not being there. But I'm not disappointed, Tsumu. I could never be disappointed in you."

Atsumu's face crumpled. "But I—"

"You're my brother." Osamu's voice was fierce. "My twin. The other half of my soul. And I'm never going to abandon you again. I swear it on everything I am. I'm going to be here—every day, for as long as it takes. We're going to get through this together."

"Together?" Atsumu's voice small, fragile—like a child asking for a promise he was afraid to believe.

"Together." Osamu pressed his forehead against Atsumu's—the way he used to when they were kids, scared of the dark. "I love you, Atsumu. I've always loved you. And I'm sorry it took me so long to remember."

Atsumu's hand found his—small and cold—and held on like a lifeline.

"Stay with me?" Atsumu whispered.

"Always."

The sun was rising outside the window, painting the sky in shades of gold and pink. A new day. A new beginning.

Osamu watched the light creep across the floor and felt, for the first time in months, something that might have been hope.
