Three weeks passed.
This was the shape of it: Tuesdays she came to the shop around noon, not because they had agreed on Tuesdays but because she seemed to appear on Tuesdays naturally, the way certain birds returned to certain trees without anyone arranging it. Thursdays they went somewhere with purpose — a records office, a maritime authority desk, a library archive — and then afterward walked without purpose, which had become its own kind of purpose. She always bought canned coffee from the vending machine near Haruiro before they left, always the same brand, always black, and always offered him one with the same expression that assumed he would say no and was mildly pleased when he said yes.
He started saying yes on the second Thursday.
The mornings were changing. Spring was tipping slowly toward the warmer side of itself, and the shop inventory shifted with it — the ranunculus making way for peonies, the tulips retiring until next year, the first of the summer stock arriving in boxes that smelled of cold storage and long distance. He found himself noting things to tell her. A particularly strange customer who had spent forty minutes choosing between two bundles of identical carnations. The sparrow that had apparently decided the signboard was a permanent address. The hydrangeas, which had not died after all, and were in fact producing new growth at the base that he hadn't expected.
He told her about the hydrangeas on a Tuesday, and she said, "I told you."
She had not said anything of the kind.
"You implied it," she said, when he pointed this out.

The three ships were the Asahi Maru, a mid-size passenger vessel running a coastal leisure route; the Himawari Princess, a larger cruise liner doing a loop between several southern ports; and a smaller charter vessel called the Shiosai that operated private bookings and kept less public records than the others.
The Asahi Maru was eliminated quickly. Its route had passed too far offshore during the relevant window for anyone to have drifted from it to Misakicho within a reasonable timeframe. The physics simply didn't support it. Kaito had worked this out with a current map and more attention to tide tables than he had previously given any subject in his life, and Nagisa had sat beside him at the library table and watched him draw the drift radii with a pencil and said nothing until he was finished, at which point she said, "You're very thorough."
"It matters to get it right."
"I know," she said. "I'm not complaining."
That left the Himawari Princess and the Shiosai.
The Himawari Princess kept comprehensive passenger records, as large commercial vessels were required to do. Getting access to those records had taken two weeks of patient correspondence with the shipping company's administrative office, a formal written request citing the specific circumstances, and one phone call that Kaito had made from the back of the shop on a Tuesday afternoon while Nagisa sat on a stool on the other side of the door pretending to read a magazine she was holding upside down.
He had not pointed out the magazine.
The response had come on a Thursday morning, forty minutes before she arrived. He had read it twice, and then set it face-down on the counter, and then picked it up and read it a third time, and then she had come through the door out of breath as usual and he had handed it to her without speaking.
She read it standing in the middle of the shop, still holding her canned coffee.
He watched her face.

The Himawari Princess manifest from that voyage listed three hundred and twelve passengers. Among them, in the records of those whose boarding had been confirmed but whose disembarkation had not, there was one name.
Tachibana Nagisa. Age listed as eighteen. Home address: Shirogane, Minato ward, Tokyo.
She stood with the letter in her hands for a long time.
The shop did its usual morning things around her. The ceiling fan turned. The freesia on the counter — he had kept freesia on the counter, he realized, since the first day she came — caught the light from the front window. The street outside was doing its bicycle bells and shutter sounds, the neighborhood waking in its ordinary way, unaware that something had just shifted inside this small building on its narrow road.
"Shirogane," she said finally. Her voice was even. Carefully even.
"Yes."
"That's—" She stopped. Tried again. "That's a real place."
"It is."
"I'm from a real place." She said it as though the concept required a moment to settle. As though until this letter she had existed in a kind of geographic abstraction — a person who had emerged from water and circumstance, with no city, no ward, no street behind her. And now there was a street. Shirogane, Minato ward, Tokyo. Specific and actual and real.
Her hands were shaking. Not much — just a fine, contained trembling that she was clearly trying to manage and mostly succeeding at.
Kaito took the letter gently from her hands and set it on the counter. Then he went to the back and came back with a glass of water, which she accepted and held without drinking for a moment before taking a slow sip.
"Eighteen," she said.
"Yes."
"I was eighteen." She looked at the letter on the counter. "On that ship. Alone? With someone? There's no — it doesn't say."
"It only lists individual passengers. Travelling companions wouldn't necessarily be noted unless they booked together." He paused. "We can find out more. This is the first thread. Now we pull it."
She looked at him.
There was something in her expression that he had not seen before — or had perhaps seen in fragments, in the quiet moments between things, but never assembled quite like this. It was not happiness exactly. It was closer to the feeling of standing at the edge of something vast and finally, after a long time of waiting, having permission to step forward.
"Okay," she said. "We pull it."

They went to the river that evening without discussing whether they would.
It had become the natural end to Thursdays — the walk to the low concrete wall, the water doing its evening things, the particular quality of the hour that made difficult things easier to sit with. He had brought the current map from the library session, folded into a square in his jacket pocket for no reason he could explain. She had bought two canned coffees and given him one without asking.
They sat for a while without speaking.
"I've been afraid of this," she said eventually. Not to him specifically — to the water, to the darkening air. "Of finding out. I didn't realize how much until just now."
"What are you afraid of?"
She thought about it honestly, which was her way — she didn't reach for easy answers.
"That whoever I was won't be who I am now," she said. "That there's some other version of me with a history and a family and a life, and she's a stranger. And I'm supposed to just — become her again." A pause. "Or that she doesn't exist anymore and I'm the only version left and that's — that's also frightening, in a different direction."
Kaito held his coffee with both hands. The metal was warm against his palms.
"You don't have to become anyone," he said. "You're already someone."
She turned to look at him. In the evening light her face was its own quiet geography — something he had been learning slowly, without meaning to, the way you learn the layout of a room you spend time in. The way the small line appeared between her brows when she was thinking. The way her shoulders dropped a fraction when she finally said something she had been carrying.
"That's the kindest thing anyone's said to me about this," she said. "And I've had five years of people saying kind things."
He didn't know what to do with that, so he looked at the river.
The two elderly women were there again, on their bench, with their wrapped paper parcel. He had begun to think of them as a fixture of this place, as permanent as the wall or the water.
"Do you think they come here every day?" Nagisa said, following his gaze.
"Probably."
"Do you think they talk, or just sit?"
He considered the question seriously. From this distance it was hard to say. They were close together on the bench, their shoulders nearly touching, and there was something in the quality of their stillness that suggested they had been beside each other long enough that the boundary between talking and not talking had become irrelevant.
"I think they don't need to decide," he said.
Nagisa was quiet for a moment.
"I want that someday," she said. Softly, not really to him. "To be somewhere long enough that it doesn't matter."
He didn't answer. The river kept moving, carrying the last of the light toward wherever light went when the day was done, and beside him she sat with her coffee and her newly-acquired home address and the long work of becoming ahead of her, and he thought that Shirogane was not so far from here, really, and that threads, once you found them, had a way of leading somewhere if you followed them with enough care.
