The lab was nearly empty, save for the warm hum of machines winding down and the last glimmers of evening sun folding through the blinds. The stainless-steel counters were cleaned to a shine, and only the scent of tea lingered—spiced, a little too bitter, over-steeped.

Akira stood at the sink, slowly wringing out a damp cloth, his movements precise. He had already cleaned his station, checked the inventory twice, and still—he hadn’t left.

He heard him before he saw him. The sound of familiar footsteps on tile, quiet but distinct. No one else walked that slowly near the end of the day. When Akira turned, he was there—hair tousled by the wind, carrying a thermos with one hand and wearing the expression he always wore around Akira: like something was about to begin.

They didn’t speak at first.

They never needed to.

The boy set the thermos down on the counter, without words. Akira didn’t touch it. Not yet. His eyes lingered on it. On him.

It had been like this for years now—since they were twelve. Since Jun had first taken Akira in, and he had found, without meaning to, a quiet rhythm in someone else’s presence. They had lived under the same roof, grown together in the same rooms. The line between affection and habit had blurred so long ago that neither of them spoke of it—not in words. But it had always been there. In gestures. In glances. In the care that slipped through routine.

He finally took the thermos and sipped. Too bitter, as always. The boy knew it. Akira didn’t correct him this time.

Instead, he set the cup down and looked at him—truly looked.

He saw not just Jun’s younger brother, not the boy he had shared notes and tea and late-night ramen with. He saw the person who had stayed. Through burnt curry and broken competitions, through silence and storm.

They had never said what they were.

But Akira knew.

He crossed the room slowly, stopping just close enough. Close enough that their shoulders might brush if one of them breathed a little deeper.

His voice, when it came, was quiet.

“You’ve always made this place feel like home.”
