The Thread Unbroken
After a week away, Osamu returns home to a house that feels wrong. His twin brother Atsumu, never one for silence, has locked himself away with a secret that will shatter their world—and Osamu will do anything to protect him.
The heat of late August in Inarizaki was the kind you couldn't escape—thick, wet, clinging. Osamu stepped off the bus, duffel slung over one shoulder, still tasting salt and sunscreen from a week at the beach with Suna. Good company, Suna. Quiet when it mattered, sharp when it didn't, never asked for more than Osamu felt like giving. A real break from the noise at home, from the weight of being a Miya twin.
The street hadn't changed. Convenience store where they'd grab onigiri after practice, the park where they'd kick a ball until the streetlights buzzed to life. The house looked the same too—weathered gate, rusted hinges, screen door that never quite caught. Osamu shoved it open and stepped inside.
"Ma. I'm back."
Her voice drifted from the kitchen, warm but distracted. "Welcome home, Osamu. Food in the fridge. Your brother's in his room."
He grunted, dropped his bag by the stairs, padded to the kitchen for water. The house felt wrong. Quiet. Atsumu was never quiet. Atsumu was noise and chaos and a laugh that could peel paint. The silence sat heavy in his chest.
He took his time drinking, washing the travel taste out of his throat. Then he climbed the stairs, already bracing for the usual assault.
Door was closed.
Osamu frowned. Atsumu never closed the door. Said he needed to "breathe the same air as his adoring public," but really, he just liked being able to yell down the stairs without getting up.
He knocked once. "Oi. Open up."
Nothing.
Knocked harder. "Tsumu. Ma said you're in there."
A pause. Then a voice, smaller than he remembered. "Yeah. Come in."
He pushed the door open and stopped.
Atsumu sat on the edge of his bed in a loose t-shirt and shorts. Hair a mess—not the usual deliberate chaos, but neglect. Eyes fixed on his phone, thumb scrolling like it was the only thing keeping him upright. But it wasn't the posture or the silence that made Osamu's stomach drop.
It was the marks.
A bruise bloomed on his neck, purple and angry, half-hidden by the collar. Another peeked from his collarbone. His wrists resting on his knees looked thin in a way they hadn't two weeks ago.
"Oi." Osamu's voice came out flat. "What the hell happened to you?"
Atsumu's thumb stopped. He looked up, and for a split second something raw and broken flashed across his face before it got smoothed over with a grin that didn't reach his eyes.
"What, miss me already? I'm fine. Had a wild summer, that's all."
Osamu's jaw tightened. "Those aren't volleyball bruises."
Atsumu's smile faltered. "Nope. They're the fun kind."
First week back at school was a nightmare dressed in navy blue.
Osamu heard it in the hallways before he saw it. Whispers coiling around him like smoke. Miya Atsumu. Did you see him? With that third-year from soccer? I heard he did it in the storage closet. On his knees. Like a dog.
He wanted to write it off as exaggeration. Atsumu had always been loud, flirty, loved attention. But this was different.
He saw it for himself on the third day.
Walking toward the gym, he passed behind the old practice building. Cruel laughter caught his attention. He stopped, peered around the corner.
Atsumu was on his knees.
A leash clipped to a cheap dog collar around his neck—the kind you buy at a pet store for a thousand yen. The other end held by a third-year Osamu vaguely recognized from the baseball team. The boy yanked it, making Atsumu's head jerk forward. The group of boys around them laughed.
"Fetch, Miya. Didn't you say you'd do anything? Crawl."
Osamu's blood turned to ice.
Atsumu's face was blank. Not embarrassed. Not angry. Empty. He lowered himself onto his hands and knees and started crawling across the concrete, the collar digging into his throat as the leash pulled taut.
Osamu didn't watch the rest. He turned and walked away, hands shaking, stomach writhing with a disgust he couldn't name.
That night, he moved his futon to the far corner of their room. When Atsumu came home late, smelling of cheap cologne and something sour, Osamu didn't look at him. Didn't speak. The silence between them grew solid, suffocating.
Days passed. Osamu avoided him at school, ignored him at home, refused to acknowledge the way his twin's eyes looked more hollow each morning. Told himself it was justified. Atsumu was doing this to himself. His choice, his reputation, his life to throw away.
But he couldn't ignore the moments.
The way Atsumu's laugh had changed—sharper, brittle, like glass about to shatter. The way he flinched when someone touched him unexpectedly. The way he stayed in the bathroom too long, long enough their mother started knocking, asking if he was sick.
And then the afternoon Osamu came home early from practice because Coach dismissed them for rain. He climbed the stairs quietly, meaning to grab a towel, and heard a sound that stopped him cold.
Coming from Atsumu's room. A sound so raw and broken it took him a moment to recognize as crying.
Not the theatrical sobs Atsumu used as a kid to get out of chores. This was something else. The sound of someone trying to hold it all in and failing. Someone drowning in a room only twelve tatami mats wide.
Osamu stood in the hallway, hand hovering over the doorknob. He could open it. Go in. Ask.
He didn't.
He walked away, and hated himself for it.
The confrontation came two weeks later, as September bled into October and the air turned cool and sharp.
They were in the room. Atsumu getting ready to go out again, pulling on a jacket too thin for the weather, running a hand through his hair. That vacant look in his eyes, deadness Osamu couldn't stop seeing in his dreams.
"Where are you going?" Osamu's voice came out harder than he intended.
Atsumu didn't look at him. "Out."
"Out where? To let someone put another leash on you?"
The words hung in the air like poison.
Atsumu's hand stilled. He turned slowly, and for a moment Osamu saw something flicker in his eyes. Pain. But it was gone before he could hold onto it, replaced by a smirk that was all wrong.
"Jealous? I could give you the guy's number if you want. He's got a—"
"I don't want to hear it." Osamu stood, fists clenched. "Do you have any idea what people are saying about us? About this family? You're a joke, Atsumu. The school's whore, and you're wearing it like a goddamn badge of honor."
Atsumu's smirk didn't waver, but his hands were shaking. "I didn't realize you cared so much about my reputation."
"I care about—" Osamu's voice cracked. "I care about not being related to someone with no self-respect. What happened to you? You used to be so fucking proud. Strutted around like king of the world. Now you let people lead you around on a leash like a dog and you just—you just take it."
The smirk finally fell.
Atsumu stared at him, and his face was a mask of something so complex and terrible Osamu almost looked away. Anger. Shame. Grief. And underneath it all, desperation so deep it looked like a void.
"You don't know anything." Atsumu's voice was quiet, hollow. "You left. Went to the beach with Suna, had your perfect little vacation, came back and decided you knew everything about me."
"I didn't—"
"You didn't ask." Atsumu's voice cracked. "You didn't once ask me what happened. You just looked at me like I was disgusting and decided I was. You've been treating me like trash since you got back, and you never once asked why."
Osamu opened his mouth to respond, but Atsumu was already gone, footsteps pounding down the stairs and out the front door, leaving silence in his wake.
The night it happened was November. First real cold of the season had settled over the town, frosting windows, turning breath into fog. Osamu had been lying awake for hours, staring at the ceiling, thinking about the look on Atsumu's face when he'd walked out.
He'd heard him come home around midnight. Heard the shower run too long. Heard the creak of floorboards as Atsumu moved around their room, settling into his futon on the other side.
But now, at two in the morning, he heard something else.
A soft, rhythmic sound. Like something being dragged across skin.
Osamu's body went cold. He lay still, listening, trying to convince himself it was nothing. House settling. Imagination. Anything.
But the sound continued.
He sat up slowly, heart hammering. The room was dark, lit only by the pale glow of the streetlight through the curtains. On the other side, Atsumu's futon was empty.
But the bathroom light was on.
Osamu got up. Legs felt like lead. He walked to the bathroom door, cracked open a few inches, and pushed.
Atsumu sat on the floor, back against the wall, legs drawn up to his chest. Left arm extended in front of him. In his right hand, a razor blade.
Blood welled from a cut on his wrist—not deep, not yet, but there. A series of thin, parallel lines ran up his forearm, some fresh and red, others older and scarred. A ladder of pain telling a story Osamu hadn't wanted to read.
"Tsumu," he breathed.
Atsumu's head snapped up. Eyes wild, wet, face streaked with tears. For a long moment neither of them moved. Then Atsumu looked down at the blade in his hand, and his face crumpled.
"I can't do it anymore," he whispered. "I can't. I can't live with it anymore."
Osamu dropped to his knees in front of his brother. Hands shaking as he reached out, carefully, slowly, and pried the blade from Atsumu's fingers. It clattered to the tile floor. He kicked it away, out of reach.
Atsumu didn't fight him. Just sat there, shaking, breath coming in ragged gasps. And then the tears came properly—ugly, raw, broken, tearing out of him like a wound that had been festering too long.
"I didn't—I didn't want to—" Atsumu choked on his own words, whole body heaving. "I tried. Tried to forget. Tried so hard. But every time I close my eyes, I see them. Feel them. And I can't—I can't make it stop."
Osamu's throat was tight. "Them? Who, Tsumu? Who did this to you?"
Atsumu's hands came up to cover his face, but he couldn't hide from the words spilling out like poison. "The obachan. The ones who came over for dinner. Mom and Dad's friends. When you were gone. They kept coming over. Dad said to be polite. He said to—he said—"
His voice broke into a sob.
Osamu felt the world tilt beneath him. He thought of summer. The endless parade of their parents' acquaintances, drinking parties stretching late into the night. The way their father always insisted Atsumu stay and "entertain" the guests because he was the charming one, the funny one, the one everyone loved.
He thought of Atsumu, fifteen years old, alone in a house full of adults who should have protected him.
"They raped me." Atsumu said the words like spitting out glass. "They said if I told anyone, they'd kill me. They said I asked for it. They said—" He stopped, a sound escaping him that wasn't quite human. "They said I was so pretty when I cried."
Osamu couldn't breathe. Room too small, walls pressing in, but he couldn't move. Could only stare at his brother, at the scars on his arms, at the hollow look in his eyes he'd been too blind and too angry to understand.
"When I came home," Atsumu continued, voice dropping to a whisper, "it was like I was still there. Could still feel their hands on me. Everywhere. Couldn't make it stop. So I started—I started doing it myself. If I could control it, if I could choose who touched me and when, maybe it wouldn't feel so bad. Maybe I could pretend it was my choice. Maybe I could feel something other than—"
He broke off, pressing his palms into his eyes.
"I thought if I was dirty enough, used enough, no one would want me anymore. And then it would stop. But it never stops. It never fucking stops."
Osamu's vision blurred. He realized he was crying, tears falling silently as he stared at the broken remains of his brother. The brother he'd ignored. The brother he'd judged. The brother he'd left alone to drown.
"You said I ruined our reputation. You looked at me like I was garbage." Atsumu's voice was small, almost childlike. "And I thought, 'He's right. I am. I am garbage. That's all I am now.'"
"Don't." Osamu's voice cracked. "Don't say that. Please."
"I can't do this anymore, Samu." The childhood nickname slipped out, long abandoned for the sharp edges of adolescence. "I can't pretend to be okay. I can't let them keep touching me. I can't keep cutting myself open just to feel something other than this. I can't. I can't. I can't."
"Then stop." Osamu reached out and grabbed Atsumu's shoulders, shaking him gently, forcing his twin to look at him. "Stop pretending. Stop carrying this alone. I'm here. I'm sorry. I'm so fucking sorry I wasn't here before, but I'm here now. You don't have to do this alone."
Atsumu stared at him, eyes red and swollen, breath shuddering. "But I—I can't—"
"We'll get help." Osamu's voice was fierce, desperate. "Find a doctor. A counselor. Someone who knows how to fix this. We'll tell someone what they did to you. Make them pay. I'll burn them alive myself if I have to."
Atsumu let out a sound that was half-laugh, half-sob. "You can't. You don't know—"
"Then tell me. Tell me everything. Don't hold it in anymore. Don't cut it out of yourself to make it stop. I'll carry it with you. Whatever it takes."
Osamu pulled Atsumu into his arms, and for a moment Atsumu stiffened, whole body a wire pulled too tight. But then he collapsed into his brother's embrace, face buried in the crook of Osamu's neck, and he sobbed.
He sobbed like he'd been holding it in for months, because he had. Sobbed like a child who'd been hurt and was finally, finally being held. Osamu held him through it, hand running through Atsumu's hair, his own tears falling into the tangled strands.
"I'm sorry," Osamu whispered. "So sorry. Should have seen. Should have asked. Should have been there."
Atsumu didn't answer. Just held on tighter, like he was afraid if he let go, he'd fall back into the void.
They stayed on the bathroom floor until the darkness outside the window began to lighten, first gray fingers of dawn creeping through the frosted glass. When Atsumu's sobs had quieted into hiccups and his breathing evened out into something closer to sleep, Osamu carefully pulled away.
"Stay here," he said softly. "I'll get the first aid kit."
Atsumu's hand shot out and grabbed his wrist. Grip weak, but desperate. "Don't leave."
"I'm not leaving. Be right back. Two seconds."
Atsumu shook his head. Eyes glassy, unfocused. "Every time someone says that, they don't come back."
Osamu's heart broke clean in two.
"I'll come back." He squeezed Atsumu's hand. "I promise."
He was back in thirty seconds with the first aid kit, a glass of water, a towel. Knelt beside his brother and gently took his arm, examining the cuts with a steadiness he didn't feel. Shallow—mostly superficial, the kind that would scar but wouldn't kill. Deep ones came later, when someone had learned how to really hurt themselves.
He cleaned them anyway, carefully, methodically, the way he'd learned in basic first aid. Atsumu winced but didn't pull away.
"Where else?" Osamu asked quietly.
Atsumu was silent for a long moment. Then he reached out and took Osamu's hand, guiding it to his thigh. Osamu felt the ridges of scar tissue beneath the fabric of his shorts—long and smooth, rivers on a map of pain.
He didn't pull away.
"Okay," he said. "We'll start here."
The sun rose fully as they sat together on the bathroom floor, surrounded by bloodied cotton balls and the remnants of a night that had changed everything. When Atsumu finally fell asleep, head on Osamu's shoulder, Osamu didn't move.
He stared at the wall and thought about a list of names. The ones Atsumu had given him in broken fragments between sobs. The ones who had smiled at their parents over dinner and then put their hands on a child.
He thought about what he was going to do to them.
But first, he had to take care of his brother.
He looked down at Atsumu's sleeping face, still streaked with tears, still too pale, still carrying the weight of everything that had been done to him. But there was something else there now. Something that hadn't been there before.
A fragile thread of trust, stretched thin but unbroken.
Osamu pressed a kiss to the top of his brother's head, the way their mother used to do when they were small and scared of the dark.
"I've got you," he whispered. "I've got you, Tsumu."
Atsumu stirred but didn't wake. His hand found Osamu's and held on.
They had a long road ahead. Doctors and police and conversations that would tear open wounds Osamu could only guess at. Days when Atsumu would want to give up, nights when the darkness pressed so close breathing felt impossible.
But they'd face it together.
They were the Miya twins.
And Osamu would burn down the world before he let anyone hurt his brother again.
