The ramen place was the kind of small that meant everyone inside immediately knew you'd walked in. Four people already seated, a man behind the counter who looked like he'd been making ramen since before Kairo was born, and a smell that hit them the moment the door slid open — rich and deep and warm in a way that was almost aggressive.
Yuki went very still on his back.
"What's that smell?" she said.
"Broth."
She didn't say anything. Just breathed it in slowly like she was trying to figure out what to do with the information.
The man behind the counter looked up. Took in Kairo. Took in Yuki on his back. Looked back down at his broth without any visible reaction whatsoever, which Kairo respected enormously.
They sat at the end of the counter. Yuki finally slid off his back and onto the stool beside him, and immediately turned to look at everything — the hanging menu, the other customers, the steam rising from bowls, the man's hands moving behind the counter with the particular efficiency of someone who had done the same thing ten thousand times.
"What do I order?" she said.
"Whatever you want."
She looked at the menu. Then at him. "I don't know what any of this means."
"Pick something with a picture."
"They all have pictures."
"Then pick the one that looks best."
She looked at the menu for a long moment with complete seriousness, like she was making a decision with real consequences. Kairo watched her from the side without meaning to.
"That one," she said finally, pointing.
"Spicy miso."
"Is that bad for a first try?"
"Depends how dramatic you are."
She turned and looked at him. "How dramatic am I?"
"Unknown," he said. "That's the whole point of the experiment."
She turned back to the menu looking mildly offended and also like she was trying not to smile.
The bowls arrived and Yuki picked up the chopsticks immediately. She held them the way someone holds them when they've seen it done but never actually done it — fingers in the wrong place, grip too tight, the whole structure fundamentally unstable.
She got a noodle halfway to her mouth and it slid off.
She stared at the chopsticks like they had personally wronged her.
She tried again. The noodles folded over themselves and went nowhere.
Kairo glanced at her once. Then without a word he reached over with his own chopsticks, picked up a clean portion from her bowl, and held it out to her.
Yuki looked at the chopsticks. At him.
He was already looking back at his own bowl, arm still extended, completely patient, like this was a perfectly normal thing to be doing and he had nowhere else to be.
She leaned forward and ate it off his chopsticks.
He pulled his hand back and ate from his own bowl. A few seconds passed. She fumbled with hers again. He reached over, picked up another portion from her bowl, held it out without looking at her.
She ate it.
He went back to his own bowl.
Yuki stared very carefully at the counter in front of her and said absolutely nothing about it.
It kept going like that. He'd eat from his bowl, glance over, and if she was struggling he'd simply reach into hers, pick something up, hold it out, and she'd eat it off his chopsticks and he'd go back to his own like nothing had happened. Back and forth. His bowl, her bowl, his bowl, her bowl. Calm and unhurried and acting like this was just the obvious solution to the problem.
She said nothing. Her ears were pink. They had been for a while.
She got through half the bowl before she tried the broth directly and inhaled slightly too fast and ended up with her eyes watering, setting the bowl down.
"Hot," she said.
"Broth usually is."
"You could have said something."
"I assumed you'd figured that out from the steam."
"The steam was very far away from my face and the bowl was right at my face."
He reached over without looking and handed her his water glass. She took it and drank and then sat there for a second reassessing her choices.
"Still good though," she said.
"I know."
"Don't say I told you so."
"I didn't say anything."
"You were thinking it."
He was, a little. He went back to eating.
She picked the chopsticks back up and kept going, more careful this time, and they sat like that for a while in the warm small space with the sound of the broth simmering and the street outside going about whatever the morning after the world changed looked like. Fine. Genuinely fine. The kind of quiet that didn't need anything added to it.
Then Yuki paused.
"Kairo," she said.
"Mm."
"People are looking at us."
He looked up. She was right. The four other customers had the very specific posture of people trying not to look directly at something while absolutely looking at it. One of them — a woman in her fifties — had her phone angled down but the screen was clearly facing them.
He looked at the woman. She immediately looked at her bowl.
Yuki leaned slightly toward him. "Do you think they recognised us?"
"The footage has probably been everywhere for the last twenty minutes."
She thought about this. "We do look pretty recognisable."
"White hair and red eyes, yes."
"Should we leave?"
He looked at his bowl. Still half full. He looked at Yuki's bowl. He looked at the woman with the phone who was doing a very poor job of being subtle.
"After we finish," he said.
Yuki looked at him. Something about the complete unbothered flatness of it made her turn back to her bowl with the expression of someone who had decided she agreed and was glad she did.
He reached over and held out another bite from her bowl.
She ate it without looking at him.
They were nearly done when Kairo's phone buzzed.
He picked it up. A message from a number he hadn't saved but recognised.
it's rina. are you watching the news. is that you and the girl from last night on every channel right now
He set the phone face down.
Yuki glanced at it. "Who's that?"
"Rina."
Yuki's chopsticks paused for just a fraction of a second. "What did she say?"
"She wants to know if we're on the news."
Yuki looked at the man behind the counter, who was very focused on something in the kitchen. Looked at the other customers. Looked back at Kairo.
"Are we on the news?" she said.
"Probably."
She leaned over and looked at his phone face down on the counter. "Aren't you going to answer her?"
"Later."
"She's going to worry."
"She worries regardless."
Yuki considered this. Then she went back to her bowl and got the last noodles, still struggling a little, and he still reached over and held out the difficult ones without being asked.
She got to the broth at the bottom and looked at it. Looked at him. He was watching.
"Don't," he said.
She picked the bowl up and drank the rest of the broth.
He looked at the ceiling briefly.
She set the bowl down with a deeply satisfied expression and then immediately winced because it had still been hot. Her eyes watered again.
"Worth it," she said, before he could say anything.
"You have broth on your face."
She blinked. Reached up and touched her cheek. Missed completely. He reached over and pressed his thumb to the corner of her mouth, once, without making a thing of it, and took his hand back.
Yuki went very still for approximately two seconds.
Then she looked forward at the counter with the careful composure of someone reassembling themselves and said nothing at all.
He left money on the counter and stood up.
"Ready?" he said.
"Mhm," she said, in a voice that was almost entirely normal.
She got on his back before they even reached the door, arms around his neck, chin on his head, legs off the ground.
The man behind the counter glanced up as they left.
"Come back," he said simply. The first thing he'd said the entire time.
Yuki turned and smiled at him over Kairo's head, bright and genuine, and the old man looked briefly like he wasn't sure what to do with that and then went back to his broth.
The walk home was quiet.
Not the uncomfortable kind — just the kind that happened when nothing needed to be said. The city around them was doing the thing cities did when something had shifted: still functioning, still moving, but with the slightly unsteady quality of something that knew the ground had changed and hadn't figured out what to do about it yet.
Yuki watched all of it from his back.
They turned onto their street. Their building was halfway down the block, ordinary and unremarkable, the kind nobody looked at twice.
"Kairo," she said.
"Mm."
"Thank you for today."
"We fought a floor boss and you burned your mouth on broth."
"I know," she said. "It was a good day."
He didn't answer. But she felt his shoulders settle under her in that small particular way they did when something had landed right, and she smiled into the top of his head where he couldn't see it.
They were almost at the building entrance when the door opened and Rina stepped out, keys in hand, clearly on her way somewhere. She stopped the second she saw them.
Kairo stopped.
Yuki stopped — or rather Kairo stopped so Yuki stopped with him, still on his back, chin on his head, legs dangling.
Rina looked at Yuki. At the white hair. At the red eyes. The matching everything. And then, with the unstoppable momentum of someone who had arrived at the same conclusion three times now and saw absolutely no reason to revise it —
"She's your sister," Rina said.
The silence that followed had a very specific quality.
Yuki lifted her head slowly off his. Kairo's expression didn't change but something behind his eyes did — the particular flatness of someone who has said the same thing enough times that saying it again feels genuinely unreasonable.
"Rina," he said, and the single word carried more tired weight than most sentences.
"She isn't,", "Im not," Yuki said, at exactly the same time, with the calm patience of someone who has completely run out of it.
"But—"
"She's not my sister," Kairo said.
"We've said this," Yuki added.
"Multiple times," Kairo said.
"Since yesterday," Yuki said.
Rina looked between them. At the way they'd finished each other's sentences without noticing. At the matching white hair and matching red eyes and the matching expression of two people who were very tired of this specific conversation.
She opened her mouth.
"Don't," Kairo said.
Rina closed it.
Yuki, with the air of someone making a point, turned her face and pressed her lips to Kairo's cheek — brief and warm and completely unbothered — then settled her chin back on top of his head and looked at Rina pleasantly.
Rina stared at her.
The keys in her hand jingled faintly as her grip shifted.
"Okay," she said finally, in a very small voice. "Not your sister."
"Thank you," Yuki said.
Kairo said nothing. He walked through the door. Yuki gave Rina a small two-fingered wave over his shoulder as they passed, the hoodie sleeve flopping over her hand.
Rina stood alone in the entrance and watched them disappear into the stairwell. The door clicked shut.
She stood there for a long moment.
Not siblings.
She was going to have to stop saying that.
She went back inside.
Upstairs, Kairo unlocked the apartment and Yuki slid off his back the moment they were inside. She came and folded herself into the chair beside his at the desk, legs pulled up, shoulder against his arm, hand finding his sleeve.
She was quiet for a moment.
Then — "You fed me the entire time."
He didn't look up. "You weren't eating."
"I was trying to eat."
"You were failing to eat. There's a difference."
She looked at the side of his face. "With your own chopsticks. From my bowl. The whole time."
He said nothing. But the corner of his mouth moved — just barely, just once, the smallest possible concession in the direction of a smile.
She turned back to the laptop screen with the expression of someone filing that away somewhere permanent.
A moment passed.
Then, very casually, without looking at him — "You went still."
"Mm."
"When I — you went still."
"I'm aware."
She looked at the screen. He looked at the screen. Neither of them said anything else about it.
But her grip on his sleeve tightened just slightly and he let her, and outside the window Tokyo continued to figure itself out, and inside the apartment was warm and quiet and exactly the right size.
