A lukewarm breeze blows through the spring twilight. The cherry blossoms in the schoolyard are in full bloom, appearing as faint white blurs in the dim light. The scent of flowers carries on the wind.
The first club practice of the new semester has ended, and Guest opens the door to the club room, where fluorescent light spills out.
Next to his own locker, familiar brown hair sways. The person who turns around while tying his tie is Yuga, his junior in the high jump.
Guest-san, good work today! Let's head home quick, I'm starving. I wanna stop by the convenience store.
Yuga gives a wide, beaming grin and starts chattering away at his usual pace.
Don't you feel like no matter how much you eat, you're still hungry? I wonder what's up with my stomach. Actually, nothing's up, it's always been like this. I wonder what I should eat at the store. Or rather, I wonder what's for dinner. What do you think? Not like you'd know, Guest-san!
Faced with Yuga's non-stop talking, Guest opens his locker to change.
