The night before the trip, Eadlyn packed three times.
Not because he forgot things — he didn't — but because packing gave him something to do with the anticipation, which had arrived earlier than expected and didn't have anywhere else to go. First-aid kit. Rope. Lantern. Hiking shoes he'd bought two weeks ago and worn around the villa to break in, which Sakura had watched without comment and Reno had watched with the suppressed approval of a man who recognised preparation when he saw it.
He'd never been camping. Not once. The closest thing in his life to sleeping outside was a school trip to the Lake District when he was thirteen, which had involved a very solid cabin and a girl in his year crying about a spider for forty minutes. This was different. This was a mountain, a waterfall, a clearing wide enough for telescopes, and people he'd known for two months who somehow already felt like they'd been there longer.
He stood at the station at seven forty-five with everything he'd packed, which was more than necessary and less than embarrassing.
Ken arrived at seven forty-six with a bag of convenience store snacks and the energy of someone who had slept perfectly and found this entirely normal. He looked at Eadlyn's bag. Looked at his own. Said nothing, which was more generous than saying something.
Manami came at seven fifty, her bag the right size, her hair done with the particular neatness of someone who considers being presentable a form of respect for the people around her. She looked at Eadlyn's bag too.
"First time camping?" she said.
"Is it obvious?"
"A little." She smiled in the way that meant: yes, completely, and it's fine. "You'll lose about a third of that before we reach the waterfall. You'll be glad you brought the rest."
Rin arrived exactly at eight. Not at seven fifty-nine, not at eight-oh-one. She assessed the group with the efficiency of someone running a calculation, registered Ken's snack situation and Eadlyn's overpacking and Manami's presence, and said: "Train's in four minutes."
They got on the train.
What Eadlyn noticed on the train — and this was the thing about being around people he'd spent months learning — was how each of them occupied the space differently.
Ken sat the way he always sat, taking up slightly more room than strictly required, not from rudeness but from a kind of physical generosity — as though his body had decided the world was big enough to be comfortable in. He opened the snack bag almost immediately and distributed things without asking whether people wanted them, because in his experience people usually did and asking introduced unnecessary friction into a simple act of giving.
Manami sat with her bag on her lap and her hands folded over it, watching the city slide past the window. She wasn't closed — she'd answer if you spoke to her, and had been, was friendly, was warm. But there was a quality to her stillness that Eadlyn had been trying to name for weeks. It was the stillness of someone who was used to being observed and had decided, a long time ago, that the most elegant response to being watched was simply to give nothing away. Not performance. Just — composure as a choice made so long ago it had become instinct.
Rin ate one of Ken's crackers and read something on her phone. Her posture was the same on a train as it was in a classroom as it was, presumably, everywhere — straight, self-contained, taking up exactly the space she was allocated and no more. He'd noticed that she rarely initiated conversations but always had something to say when they reached her. She listened thoroughly. Remembered everything. The soy sauce on the camping grill — you mentioned it once, I'm not careless — was not an anomaly. She catalogued things about people she cared about with the same precision she applied to historical timelines.
He found himself wondering, not for the first time, what it cost her to carry that much attention and show so little of it.
The mountain path started easy — wide, well-marked, the kind of trail that had been walked enough times to know it was expected. Birds. The quality of light through trees. The sound of effort becoming the rhythm of it.
Ken and Eadlyn carried the tent supplies. Rin and Manami took the barbecue gear. After twenty minutes, Manami's breathing changed — not laboured exactly, but working harder than she'd expected. She didn't say anything about it. Her jaw set slightly, which was her version of digging in.
Eadlyn watched this without watching it, if that makes sense. He'd learned that Manami didn't want to be noticed struggling. Not because she was proud in a brittle way — more that being noticed struggling meant someone might offer to help, and offering to help meant she'd have to accept or decline, and either option required acknowledging the struggle out loud, which she'd rather not do.
So he just slowed the pace. Not dramatically. Just slightly. Adjusted the route marginally toward the flatter side of the path. Gave her the incline without the acknowledgment.
She noticed. Didn't say anything. But a few minutes later, when they reached the clearing, she glanced at him sideways with an expression he was getting better at reading — the one that meant: I see what you did. Thank you for not making it a thing.
He looked at the view and said nothing, which was the correct response.
The waterfall was modest and entirely indifferent to being modest. It came down through rock and tree-shade into a shallow pool that caught the afternoon sun in moving pieces, and the sound of it — not roaring, just continuous, the sound of something that has been doing this for longer than anyone present has been alive — filled the clearing the way good music fills a room.
"Ken," Eadlyn said. "You didn't tell me."
"I told you it was worth the climb."
"That doesn't cover—" He looked at the light on the water. "That doesn't cover this."
Ken, pleased, said nothing. There were things he let land without comment.
They changed — the informal geography of two groups, girls one side, boys the other, the understanding of it unremarked upon. Eadlyn came back to find Rin standing at the edge of the pool with her arms crossed, swimsuit the same no-nonsense sporty kind she probably wore to practice, her posture saying exactly what it always said: I am here, I am capable, the rest of you can proceed accordingly.
And then Eadlyn walked to the pool's edge and stopped, and Rin registered this and said, flatly: "You can't swim."
Not a question.
"How did you—"
"The way you're standing." She didn't elaborate. Just turned. "Follow me. Shallows first."
What followed was the most efficient swimming lesson Eadlyn had ever received, which wasn't saying much since it was also the only one. Rin taught the way she did everything — no wasted words, no encouragement that wasn't earned, correction delivered quickly and without apology. She said arm, not shoulder and trust the water, stop fighting it and once, when he finally got a basic stroke working, better — which from her carried the weight of something much longer.
He was aware, during it, of the specific kind of patience she was showing him. Rin was not patient with things she didn't care about. She dismissed those quickly and cleanly. This — standing in the shallows, watching his form, repeating arm, not shoulder for the third time without irritation — was something else. He filed it carefully, the way he filed all things he didn't yet know what to do with.
Ken organised the race with the enthusiasm of someone who has decided that competition is love expressed loudly.
Eadlyn came last. By enough distance that there was no ambiguity about it.
Rin won, which surprised no one, and turned with the particular expression of someone who has been waiting to deploy a decision.
"My request," she said.
"Yes," Eadlyn said, with the resignation of the correctly defeated.
She looked at him. Then — and this was the thing he didn't quite expect — she didn't ask for something absurd or embarrassing. She looked at the water, then back at him, and said:
"When you lived in the UK. Was there a girl. In your neighbourhood. That you used to play with."
The question arrived strangely. Not the words themselves — the texture of them. The way she asked it while not quite looking at him, the deliberate casualness that was doing a lot of work.
Ken made a sound. Manami's expression shifted into something she then adjusted.
Eadlyn looked at Rin.
She was looking at the water.
He thought about this for a moment — not what to answer, but what the question actually was. Because it wasn't really a question about a girl in the UK. It was a question shaped like that to carry something else. Something about whether paths crossed twice. Whether a memory she'd been carrying had an address.
"There was Lily," he said. "We played together a bit. I moved before either of us were old enough to really remember."
Rin nodded. Said nothing.
"Why?" he asked.
"Nothing." She walked back toward the edge.
"I visited the UK once. When I was small. I remembered a boy." A pause. "Probably wasn't you."
She said it the way you say things you've decided are probably not important, which is exactly how you say things that are.
He didn't push. Some doors you knock on once and then wait.
