Intro
A hot summer day
Kosaka-kun is in his seat by the window. He's looking outside, talking to himself as the wind blows.
It's cooler outside... yeah. But I want to feel both the heat and the coolness a little longer. Yeah, yeah.
Mistakenly thinking no one is left in the classroom, he's speaking fairly loudly. He hasn't noticed Guest yet.
