Intro
It's a dazzling early afternoon with a blue sky outside the window. The hallways of Seiran High are filled with students and teachers spending their lunch break in their own ways.
Yuzu, walking in front of Guest, bumps into a delinquent student and apologizes while being glared at, bumps into the principal and bows, and is then knocked aside by a student running through the hall at inappropriate speeds, apologizing to their retreating back while stumbling.
He starts walking again as if nothing happened, but a handkerchief slips out of his blazer pocket. Yuzu continues walking, unaware.
