The Door Left Ajar

The key turns. Click. Echoes through the dim apartment. Osamu Miya steps inside, shrugs off his coat, toes out of his shoes.

The place is too quiet. Heavy curtains swallow the late autumn twilight, leaving only thin slants of grey light across the hardwood floor. Air smells like stale coffee and something metallic—copper, maybe. Nags at the back of his throat.

"Atsumu?" His voice falls flat in the silence. No answer.

He passes the kitchen island, the couch with a crumpled throw blanket, the half-empty glass on the coffee table. Bedroom door ajar, sliver of light from the bathroom beyond.

He stops at the threshold. Listens. A soft hiss of breath, then water trickling. His twin's home.

He knocks once on the doorframe before pushing it open.

"Atsumu, you forget we had dinner plans? I've been waiting at that ramen place for—" The words die in his throat.

Atsumu's at the sink, one hand braced on the counter, the other pressing an ice cube wrapped in a dish towel to his cheek. Split lip gleams wet and red in the mirror light. Bruise under the ice already darkening—purple and angry against pale skin.

"Ah, Samu." Atsumu's smile flickers on—too bright, too quick. "Sorry, got held up. Lost track of time."

Osamu's feet root to the floor. He's seen that smile before—on their mother's face, years ago. When she'd laugh too loudly, say she'd tripped on the stairs. Wear long sleeves in July. Flinch at their father's footsteps.

"What happened to your face?" Low, hard. Not asking. Demanding.

Atsumu waves a hand. "Walked into a door. Clumsy me, right?" He turns back to the mirror, dabs at his lip with the towel. The ice cube trembles in his grip. "Don't worry about it. Wanna order takeout? I'm craving that spicy pork bowl from—"

"Atsumu." He steps into the bathroom, closes the door behind him. The latch clicks. Atsumu flinches. "Look at me."

Atsumu doesn't. Stares at his reflection, at the bruise flowering across his cheek, at the way his fingers shake. "Samu, really, it's nothing. Just a stupid accident."

"Since when do you walk into doors? You got reflexes like a cat." Osamu reaches out, catches Atsumu's wrist, pulls the towel away. The bruise is livid—spreading from cheekbone to jaw. Split lip fresh, oozing a thin line of blood. "This ain't no door."

Atsumu's smile falters. He pulls his hand free, turns away, busies himself with the faucet. Hot water runs. Steam curls, fogs the mirror. "Don't start, Samu. Please."

"Where is he?"

The question hangs like smoke. Atsumu's shoulders stiffen. His hand hovers over the tap, not quite turning it off.

"Rin's at practice. Late session. He'll be back in an hour or so." The name comes out soft, almost reverent. Like he's trying to convince himself it's still safe to say it.

Osamu's jaw tightens. Suna Rintarou. His best friend since middle school. The lanky, deadpan setter who'd always been there, quiet and steady. Who'd stood beside them at their mother's funeral. Who'd promised to take care of Atsumu when they got married two years ago.

The one who put that bruise on his twin's face.

"Did he do this?"

Atsumu's breath hitches. He turns off the water. Sudden silence is deafening. "It was an argument," he whispers, still not meeting Osamu's eyes. "It got out of hand. He didn't mean to—it was an accident."

"An accident." Osamu repeats the word like it tastes bitter. "You sound like Mom."

That gets Atsumu's attention. He whips around, eyes wide and wet. "Don't. Don't you dare compare—"

"Then tell me the truth." Osamu steps closer, close enough to see the red rims of Atsumu's eyes, the dried tear tracks on his cheeks. "How long has this been going on?"

Atsumu's lips part, but no sound comes out. He looks down at his own hands, at the faint tremble in his fingers. When he speaks, his voice is barely audible. "Not long. Just... a few months. After we found out about the baby." His hand drifts unconsciously to his stomach, still flat beneath his loose shirt.

The baby. Osamu had been thrilled when Atsumu told him. He'd hugged his brother and joked about being the favorite uncle. He'd seen Atsumu's smile, genuine and bright. But now he sees the shadow underneath—the exhaustion, the fear, the way Atsumu holds himself like he's waiting for the next blow.

"Why didn't you tell me?"

"Because I was ashamed." Atsumu's voice cracks. He sinks onto the closed toilet lid, buries his face in his hands. "Because I thought I could fix it. Because he promised it wouldn't happen again. He always promises."

Osamu crouches in front of him, rests his hands on Atsumu's knees. "Listen to me. I'm getting you out of here. Tonight."

Atsumu looks up, startled. "What? No, Samu, I can't just—"

"You can. You will."

"He's my husband. He loves me." The words tumble out desperate, rehearsed. "He's just stressed about the baby, about becoming a father. He didn't mean it. He's not like Dad. He's not."

Osamu's chest constricts. He remembers the sound of their father's fists against their mother's ribs. The way she'd always made excuses for him, too. Love and fear intertwined until she couldn't tell them apart anymore.

"You're carrying his child, and he hit you in the face. There's no excuse for that."

Atsumu's tears spill over, silent and hot. He wipes them away with the back of his hand, smearing blood from his lip across his knuckles. "I don't know what to do."

"You don't have to figure it out alone." Osamu squeezes his knees. "I'm here. I'll always be here."

The front door clicks open.

Both twins freeze. Footsteps cross the apartment floor—slow, deliberate, familiar. A voice calls out, lazy and flat, "Tsumu? You home?"

Atsumu's face goes pale. He looks at Osamu with wide, pleading eyes. "Please don't say anything. Just let me handle it."

Osamu stands, jaw set. "No."

He pushes open the bathroom door and walks into the living room. Suna is there, shrugging off his gym bag, his hair damp from a shower. He looks up. His expression shifts—surprise, then something colder, more guarded.

"Osamu. Didn't know you were coming over."

"Clearly." Steel in his voice. "We need to talk."

Suna's eyes flick past him, to where Atsumu is emerging from the bedroom, still holding the bloodied towel. The bruise on his cheek is impossible to hide. Suna's face doesn't change, but his posture tightens almost imperceptibly.

"I see." He sets his bag down on the couch, calm and deliberate. "You're going to make a big deal out of this."

"A big deal?" Osamu's voice rises. "You put your hands on my brother. On your pregnant wife. And you're calling it a big deal?"

Suna's eyes narrow. "You don't know what happened."

"Then tell me. Enlighten me." Osamu steps closer, hands balling into fists at his sides. "Because from where I'm standing, I see a bruise on his face and a split in his lip. I don't give a damn about your excuses."

Atsumu moves between them, hands up. "Stop. Both of you, just stop. Please."

"Stay out of this, Atsumu." Suna's voice low, controlled. Threatening. "This is between me and your brother."

"No, it's between you and me." Osamu shoves Atsumu gently aside, steps toe-to-toe with Suna. Same height, but Osamu's shoulders broader, his anger giving him an uncomfortable edge. "You're going to explain yourself right now, or I swear to God, I'll call the cops."

Suna's jaw flexes. He looks at Atsumu, then back at Osamu. Something ugly flickers in his eyes—resentment, jealousy, fear. "Fine. You want to know? It was an argument. About you."

Osamu blinks. "Me?"

"You're always here. Always calling. Always the one he runs to." Suna's composure cracks, voice rising. "I'm his husband. I'm the one who's supposed to be his partner. But every time he has a problem, every time he's upset, it's 'Samu this, Samu that.' Do you know what that's like? To feel like a third wheel in your own marriage?"

Atsumu's breath hitches. "Rin, that's not—"

"Shut up." Suna whirls on him, and Atsumu flinches, shrinking back. That flinch tells Osamu everything he needs to know.

"We were talking about the baby," Suna continues, voice trembling now. "And he said he wanted you to be there for the birth. He said he needed you there because you're his twin and you understand him better than anyone. His family. Not me. Never me."

"So you hit him." Osamu's voice quiet, deadly.

"I didn't mean to!" Suna's composure shatters. "It was a slap. One slap. I lost control because he kept praising you, kept pushing. I just wanted him to see me. I wanted him to need me the way he needs you."

Atsumu sobs—a broken sound. "I do need you. I love you. That's why I stayed."

"Love doesn't leave bruises." Osamu grabs Suna by the collar, slams him against the wall. The impact rattles a picture frame—their wedding photo. Atsumu screams.

"Let go of me!" Suna struggles, but Osamu's grip is iron.

"You listen to me, and you listen good." Osamu's voice is a growl, low and dangerous. "You are never going to touch him again. You're not going to call him. You're not going to come near him. I'm taking him away from here, and if I ever see your face again, I'll make sure you regret the day you were born."

Suna's eyes wide, wild. "You can't do that. He's my husband. That baby is mine."

"And you're a coward who hits someone smaller than him." Osamu shoves him harder against the wall. "Atsumu, start packing. Now."

Atsumu stands frozen, tears streaming down his face. His hands pressed to his belly, protecting the life growing inside him. "Samu, please. Don't do this. He didn't mean it."

"He meant it enough to do it." Osamu's voice cracks, just a little. "You deserve better than this. You know you do."

Suna's resistance crumbles. He slides down the wall, legs giving out, sinks to the floor. His face crumples, and for the first time, Osamu sees grief there—real, ugly grief.

"I love him," Suna whispers, staring at his hands. "I love him so much it scares me. And I hate myself for what I did. I hate that I'm turning into my father."

Osamu releases him, steps back. His hands are shaking. "Then get help. But you're not going to do it while he's still here."

Atsumu hasn't moved. He's looking at Suna on the floor, at the man he married, the man he promised to spend his life with. Love and fear swirl in his eyes, tangled and inseparable.

"Rin…" His voice breaks.

Suna looks up, tears on his cheeks too. "I'm sorry. I'm so sorry. Please don't go. I'll change. I swear I'll change."

Osamu puts a hand on Atsumu's shoulder. "Don't. Don't listen to him."

Atsumu closes his eyes. A single tear slips down his cheek, tracing the line of his bruise. Then he nods—a tiny, broken movement. "Okay."

He walks past Suna without another word, into the bedroom. Osamu follows, shoots one last glare at the man on the floor.

The packing is quick, silent. Atsumu throws clothes into a duffel bag with mechanical efficiency. Doesn't look at the wedding photo on the nightstand. Doesn't look at the bed they shared.

Suna appears in the doorway, his face blotchy and red. "Atsumu, please. Don't leave. We can figure this out. We can go to counseling."

Atsumu stops, zipping the bag. His hand rests on his stomach. "I need to protect my baby. Even if it means leaving you."

He walks past Suna, out of the bedroom, through the living room. Osamu takes the bag from him, puts a steadying hand on his back.

At the door, Atsumu pauses. Looks back at Suna, still standing in the bedroom doorway, broken and lost.

"I loved you," he says, so quietly it's almost a whisper. "I loved you so much."

Then he steps out into the hallway, and Osamu closes the door behind them.

The apartment is silent. The door clicks shut, the lock doesn't catch—Osamu left it ajar, a final, deliberate gesture. Cold air seeps in from the hallway.

Suna stands alone in the dim living room. The wedding photo lies face-down on the floor, the glass cracked. His hands hang limp at his sides.

He takes a step toward the door, then stops. Nothing left to chase. The ghost of Atsumu's scent lingers on the pillow, on the sheets. The baby's room is half-decorated, a crib still in its box.

Suna sinks onto the couch, elbows on his knees, head in his hands. The silence is absolute.

He didn't mean to. He never meant to. But the words empty in the hollow apartment, and no one is there to hear them.

Outside, the autumn wind rattles the windows. The door remains ajar, a sliver of darkness in the dim light.
