Welcome Home

The door to Osamu’s apartment clicked open before Atsumu could knock. She stood in the dim hallway light, one hand gripping her duffel bag strap, the other steadying herself on the crutches the surgeon had insisted on. Her knee ached—a dull, persistent throb that beat in time with her pulse.

Osamu stood in the doorway, a dish towel over his shoulder, his face giving nothing away. They looked at each other for a long second. Then he stepped aside.

“Took you long enough. Train was delayed?”

“Just the last transfer.” Her voice came out thinner than she wanted. She cleared her throat. “Sorry. I know this is—”

“Don’t.” He cut her off, already turning and walking back inside. “Couch is ready. New sheets. Pillows are kinda flat, but it’s better than nothin’.”

Atsumu hobbled in, closing the door with a soft click. The apartment smelled like rice vinegar and sesame oil, with an undertone of something savory that had probably been simmering all afternoon. Small but tidy—kitchen counter cluttered with Onigiri Miya stuff, a worn leather couch against the wall, a low kotatsu table with two cushions. Everything clean in the way that meant Osamu had tidied specifically for her.

Her chest tightened.

“You didn’t have to go to all this trouble,” she said, dropping her duffel near the couch. “I can sleep on the floor. I don’t wanna mess up your routine.”

Osamu was already pulling a blanket from the closet—a thick navy thing that smelled faintly of fabric softener. “Shut it,” he said without heat. “You’re stayin’ on the couch. I’m not havin’ you sleep on the floor with a knee like that. Doctor said you gotta keep it elevated.”

He tossed the blanket onto the cushions and turned to face her fully. His eyes swept over her once—the oversized hoodie, the way she held herself rigid even on crutches, the careful distance she kept from every surface. Something flickered in his gaze, but it was gone before she could name it.

“Make yourself at home,” he said. “Really. I mean it.”

Atsumu nodded, but didn’t move. She stood there in the center of his living room, feeling like a trespasser.

---

The first night was the worst.

She couldn’t settle. She sat on the edge of the couch for an hour after Osamu went to bed, listening to the old apartment’s creaks and murmurs. The ice pack the hospital had sent her home with had melted into a puddle of lukewarm water, but she didn’t ask for fresh ice. She didn’t want to open the refrigerator, didn’t want to touch anything, didn’t want to leave any trace of herself in this space that wasn’t hers.

She slept in her clothes—the same leggings she’d worn on the train, the same oversized sweatshirt. She woke stiff and cold at three in the morning, the knee throbbing. She found a bottle of pain relievers in the bathroom cabinet without turning on the light, swallowed two dry pills, and crept back to the couch like a thief.

She didn’t sleep again.

At 5:47 AM, the first gray light bleeding through the curtains, she carefully folded the blanket into a perfect square. Smoothed the sheets on the sofa cushion, tucked the edges under the foam. Then she limped to the kitchen—quiet, so painfully quiet—and started on the dishes from last night.

Osamu found her there an hour later, sleeves pushed up to her elbows, scrubbing a stain on the counter so hard her knuckles had gone white.

“What the hell are you doin’?”

Atsumu flinched. She hadn’t heard him come in. She turned, clutching the sponge to her chest like a shield. “I just thought I’d—”

“Those are mine. I was gonna do ’em after breakfast.” His voice was flat, but there was an edge beneath it. He crossed the kitchen in three strides and took the sponge from her hand. “Stop. Sit down.”

“I’m fine,” Atsumu said, but her voice cracked. “I can help. You’re lettin’ me stay here, the least I can do is—”

“The least you can do is rest.” He held her gaze, steady and unyielding. “You just got out of surgery, dumbass. You’re not a maid.”

Atsumu’s jaw tightened. She wanted to argue, but her throat was too thick. She retreated to the couch without another word and sat there, hands folded in her lap, as Osamu silently finished the dishes and started making rice.

By the third day, a routine had settled—stiff and fragile, like a scab that hadn’t quite healed.

Atsumu woke before Osamu every morning. She made the bed. She cleaned the bathroom—wiped down the sink, the shower tiles, the mirror. Always after her shower, when steam fogged the glass, so she could be sure no stray hair or water mark would betray her presence. She folded her towels into the smallest possible squares and buried them deep in the laundry basket.

She wore oversized hoodies and loose sweatpants. Never anything form-fitting, never left the bedroom in just a T-shirt. She’d spent six years learning how to disappear into her own body, and that skill had become a second skin.

Osamu watched her from the kitchen doorway, a cup of tea cooling in his hands. He didn’t say anything. But she felt his gaze like a weight.

On the fourth day, the careful choreography shattered.

It was late afternoon. Atsumu had been searching for the ibuprofen she’d left on the bathroom counter, but it wasn’t there. She’d been so careful to keep her pain relievers hidden—didn’t want Osamu to worry, didn’t want to seem weak—but now the knee was screaming, a hot sharp spiral that made her vision blur at the edges. She rummaged through the medicine cabinet, then the drawer beneath the sink.

Nothing.

She must have left the bottle in the living room. She turned to grab her crutches—but she’d left them propped against the couch. The bathroom door was half open. She thought Osamu was in the kitchen; she could hear the clatter of pots.

She took two steps toward the door—and Osamu appeared in the hallway, a head of cabbage in his hand, clearly heading to the kitchen from the small pantry.

He stopped. Atsumu stopped.

She was wearing only a sports bra and loose cotton shorts. The bra was simple and utilitarian, the kind she’d bought from an online store that specialized in activewear for transgender athletes. She’d been trying to find the right fit for months. The surgical scar on her knee was a red angry line, and the binder she’d worn through high school had left faint marks on her ribs that she knew were visible under the harsh fluorescent light.

Osamu’s eyes met hers. Then they flickered down, just for a fraction of a second, and away.

“Sorry,” he said, barely above a mumble. He turned and walked back to the kitchen without another word.

Atsumu stood frozen. The blood roared in her ears. She grabbed the first shirt she could reach—a sweatshirt draped over the bathroom doorknob—and yanked it over her head, pulling the hood up even though her hair was still damp.

She didn’t come out of the bathroom for ten minutes. When she finally did, she’d put on a long-sleeved shirt and loose joggers and slippers. She couldn’t look at him.

Dinner was silent. Osamu had made salmon ochazuke—her favorite, from when they were kids. She ate mechanically, nodding when he asked if it was good, not tasting a thing.

He tried to talk to her. “How’s the knee feelin’?”

“Fine.”

“You need more ice?”

“No.”

“Physical therapy starts next week, right?”

“Mm.”

He put down his chopsticks. “Atsumu.”

She looked up, startled. He almost never called her by her name anymore—not since her transition. It was always a grunted “hey” or “you” or, on rare good days, “my dumb sister.” But hearing her name out of his mouth, with that quiet weight behind it, made her freeze.

“How are you really feelin’?” he asked. “Not about the knee. About… everything.”

Atsumu’s throat closed. She picked up her tea and took a sip, letting the warmth burn her tongue. “I’m fine,” she said again.

Osamu stared at her for a long moment. Then he picked up his own bowl and finished his dinner in silence.

---

The pattern continued.

Atsumu cleaned. She hid. She made herself small. The apartment was spotless—spotless in a way it had never been when it was just Osamu living there. The counters gleamed. The bathroom smelled like bleach and citrus. The couch cushions were fluffed to the point of absurdity.

Osamu didn’t say anything. But the tension in his shoulders grew a little tighter every day.

On the sixth night, Atsumu couldn’t sleep.

The knee was bad. Not the surgical pain—that was fading—but a deep angry ache that came from pushing herself too hard. She’d scrubbed the bathroom floor on her hands and knees that afternoon, ignoring the way her kneecap protested, ignoring the voice in her head that said this isn’t your house, you shouldn’t be touching anything.

Now it was midnight, and she was lying on the couch, staring at the ceiling, unable to find a comfortable position. The pain wasn’t sharp enough to justify waking Osamu, but enough to pull her out of sleep every time she started to drift.

She gave up. Swung her legs over the edge, grabbed the sponge she’d hidden under the sink earlier, and limped to the bathroom.

The floor was already clean. She knew it was clean. But she needed to do something, needed to earn the space she was taking up, needed to—

She dropped to her knees and started scrubbing the grout between the tiles.

She didn’t hear Osamu’s footsteps. Didn’t hear him pause in the hallway, didn’t hear the sharp intake of breath. She only realized he was there when the sponge was ripped out of her hand.

“What the hell do you think you’re doin’?”

Atsumu looked up. Osamu stood over her, barefoot, wearing a ratty T-shirt and shorts. His hair was mussed from sleep. The sponge hung from his fingers, dripping water onto the floor.

“I just—” she started.

“It’s midnight. You’re scrubbin’ my bathroom floor. On your knees.” His voice was low, almost controlled, but there was a tremor in it. “You’ve been doin’ this for a week, Atsumu. You clean everythin’. You fold everythin’. You barely touch the furniture, you hide your towels, you walk around like you’re scared to break somethin’. What the hell is wrong?”

The words hit her like a slap. She scrambled to her feet, ignoring the sharp protest from her knee. “I’m just tryin’ to help! I’m a guest here, I don’t wanna be a burden, I don’t wanna—”

“You’re not a guest!” Osamu’s voice cracked. “You’re my twin. My sister. You’re not a stranger, so why do you keep actin’ like you’re stayin’ in a hotel?!”

Atsumu opened her mouth. Closed it. Something inside her chest splintered.

“I don’t know how to be here,” she whispered.

The words hung in the steamy air. Osamu’s face changed—the anger softening into something raw and unguarded.

“I don’t know how to be around you,” Atsumu continued, her voice breaking like a dam. “I don’t know how to be around anyone. You knew me as your brother for eighteen years, and now I’m… I’m this. And I’ve spent so long tryin’ to be a girl that I forgot how to just be a person. I forgot how to be me. Everywhere I go, I’m tryin’ to pass, I’m tryin’ to disappear, I’m tryin’ to be invisible so nobody looks at me twice—” She pressed a hand to her mouth, but the tears were already coming. “And now I’m in your home, and I don’t know how to be your sister because I don’t even know how to be myself anymore.”

She was sobbing now, ugly and raw, her shoulders shaking. Osamu didn’t move for a long second. Then he dropped the sponge. It hit the bathroom floor with a wet slap.

He stepped forward and wrapped his arms around her.

Atsumu stiffened. She couldn’t remember the last time he’d hugged her—years, maybe, before everything got complicated. But his arms were solid and warm, and he smelled like fabric softener and the faint grease of the kitchen, and he didn’t let go.

“You’re my little sister,” he said into her hair. “That’s all you ever gotta be.”

She broke. She sagged against him, her face pressed into his shoulder, crying so hard she could barely breathe. He held her up, one hand cradling the back of her head, the other pressed flat against her spine.

“You’re still the same annoyin’ brat who stole my pudding,” he murmured. “Nothin’ changed except you’re happier now. Well, you would be, if you’d stop cleanin’ my damn bathroom at midnight.”

A wet choked laugh escaped her. She pulled back just enough to look at him, her face blotchy and ruined.

“I’m sorry,” she whispered.

“Shut up.” He wiped at her cheek with his thumb, a rough awkward gesture. “You’re an idiot. You always have been. But you’re my idiot. Now come on. I’m makin’ you a onigiri.”

She blinked. “It’s one in the mornin’.”

“So? You think I have a schedule?”

He led her to the kitchen, his hand on her elbow, steadying her as she limped. He opened the refrigerator and pulled out leftover rice and a sheet of nori. He didn’t ask what she wanted—he just started making, his hands moving with the practiced efficiency of someone who’d made ten thousand onigiri before.

Atsumu sat on the stool at the counter and watched. The tears had stopped, but her cheeks were still wet. She didn’t bother wiping them.

Osamu finished shaping the rice and pressed the nori around it. Then he did something that made her laugh out loud—he tore a tiny strip of nori and pressed it onto the onigiri, forming two dots for eyes and a crooked little smile.

“Here,” he said, sliding it across the counter. “It has a face. That’s how you know it’s good.”

Atsumu picked it up. The rice was still warm. She took a bite, and the salt and seaweed and vinegar hit her tongue, and she started crying again.

“Dammit,” Osamu said, but he was smiling. “I can’t make ’em that good.”

She laughed through the tears. “Shut up.”

He sat down across from her and watched her eat the whole thing, his own onigiri forgotten on a plate in front of him.

---

The seventh morning dawned soft and gray through the curtains.

Atsumu didn’t wake at 5 AM. She didn’t fold the blankets. She rolled over, buried her face in the pillow—which smelled like Osamu’s lavender laundry detergent—and fell back asleep.

When she finally opened her eyes, the sun had shifted and the clock read 10:37. Her knee was stiff, but the pain was a dull throb, not a sharp spike. She stretched, grimaced, and limped into the kitchen.

Osamu stood at the stove, wearing an apron that said I’m the Boss in the Kitchen in faded kanji. He turned when he heard her.

“Oh, you’re up. Thought you might sleep till noon.”

“Don’t tempt me,” she mumbled.

He slid a plate onto the counter—perfectly grilled mackerel, a mound of steamed rice, a side of pickled vegetables, a small bowl of miso soup. Without a word, he set a pair of chopsticks next to it.

Atsumu sat down. She didn’t say thank you. She didn’t have to.

They ate in comfortable silence. The kettle boiled and Osamu poured himself a cup of tea, then one for her, sliding it across the counter without looking up from his phone. Some volleyball game highlights played at low volume.

After breakfast, Atsumu picked up her plate to take it to the sink. Osamu looked up.

“Leave it.”

“But I can—”

“You can sit down and watch the game with me. Or take a nap. Or whatever. But you’re not doin’ dishes.”

She hesitated, then put the plate down. Left it on the counter.

She didn’t make the bed.

She didn’t wipe down the shower.

She left her hoodie draped over the back of the couch—not folded, just draped, the hood hanging off the edge like a lazy tongue.

Osamu didn’t say anything, but his shoulders relaxed. A tiny, almost imperceptible shift.

In the afternoon, Atsumu asked, “Hey, you wanna watch a movie?”

Osamu looked up from the book he was reading—some thriller with a cracked spine. “You won’t make it through the first twenty minutes. You always fall asleep.”

“I won’t fall asleep.”

“You will.”

“I won’t.”

“You did at the premiere of that one movie. The one with the alien.”

“That was different. I was hungover.”

“You were asleep before the title card.”

Atsumu threw a cushion at him. He caught it, smirking.

“Fine,” he said, getting up. “But I’m pickin’. None of your weepy rom-com nonsense.”

“It’s not nonsense, it’s emotionally sophisticated.”

“It’s weepy nonsense.”

He put on an animated movie from their childhood—something they’d probably watched a hundred times. Atsumu curled up on the corner of the couch, her bad leg stretched out on the cushions. Osamu sat in the armchair at first, but after ten minutes, he moved to the couch too, putting a pillow between them.

She fell asleep twelve minutes into the movie.

He knew she would. He watched her for a moment—the way her face relaxed, the tension finally leaving her jaw. She looked younger. She looked like the kid who used to steal his pudding and then deny it with chocolate smeared on her chin.

He grabbed the navy blanket from the back of the couch and draped it over her, tucking the edges under her chin.

She stirred. “Mmm… five more minutes…”

“Sure,” he said softly. “Take your time.”

He settled back against the cushions, careful not to jostle her. The movie played on, a cascade of colors and sounds that neither of them were watching.

After a moment, Atsumu shifted. Her head slid onto his shoulder without warning, her breath evening out into a soft steady rhythm.

Osamu didn’t move. He didn’t even breathe for a second.

Then he reached down and adjusted the blanket, pulling it over her shoulder.

“Welcome home,” he whispered.

The movie ended. The credits rolled. The light through the window shifted from afternoon gold to evening amber.

Neither of them moved.
