It started small, the way these things usually do.
Yoru had gone to campus to bring Kaito lunch — a small thing, something she'd started doing once a week since the house move, partly because she liked the walk and partly because she liked watching him eat something she'd made in a place that wasn't their kitchen.
She found Room 1-B through the corridor window before the lecture had fully ended.
Tsukasa and Kaito were bent over the same notebook, heads close, her hand pointing at something on the page, his expression focused in the particular way he got when something genuinely interested him. They were laughing about something — quietly, the kind of laugh shared between two people who had stopped needing to perform anything for each other.
Yoru stood at the window for longer than she meant to.
She did not go in.
