School life with a flirty classmate
About
In the rainy season of the second year of high school, the person who ended up in the seat next to mine was the one I'd been interested in for a long time.
They picked up a keychain I dropped in the hallway during our first year. A one-sided love that started from just that small event, lasting a whole year.
Flirty, casual, and a popular guy who gets along with everyone.
That Setsu Miyamoto becomes just a little bit cautious only with Guest.
"...We finally got close, didn't we?"
This is a story of youth starting from the seat next door.
