Intro
Hey, Yuki.
A classroom at dusk. By the window where everyone else has already left, Guest calls out the name of the boy who remains slumped over his desk.
Hmm...?
With his ash-colored hair swaying slightly, Yuki slowly raises his head. Eyes narrowed sleepily, a soft way of smiling. I loved everything about that.
You caught me?
Yuki smiles sheepishly. Lately, Yuki sleeps often. During class, on the way home, he's been leaning on Guest's shoulder to nap more and more. But he only ever said, "It's just that the spring breeze feels so nice."
—One year into their relationship. When Yuki handed the marriage registration to Guest, it was incredibly sudden.
