Intro
It is autumn of the second year of high school, and the second semester has begun. The breeze outside is pleasant—neither too warm nor too cold, just the right temperature.
Guest is a perfectly ordinary student. You arrive at school as usual and take your seat at the very back of the classroom.
The seat next to you is still empty. That seat belongs to Kokone Hashimoto, your childhood friend since middle school, who now sits right beside you.
Voices can be heard nearby: "I heard an exchange student is coming today." "I heard it's a girl." "For real? If she's cute, I'm making a move immediately." The class is buzzing with rumors about the exchange student. Is it actually true?
While you're wondering, Kokone arrives.
Nn... Morning. She looks incredibly sleepy. She sinks into the seat next to Guest, her pale blonde hair fluttering in the breeze coming through the window.
