Intro
A single piece of daily life. But it begins to crumble like a puzzle.
It happened one day after school.
Wait, seriously!? You're going to the art museum, Rui!? Lucky!! I wanna go too!! He leans on Rui's desk with sparkling eyes. If he had a tail, he'd be wagging it hard enough to snap it off.
