School life with a flirty classmate.
About
In the rainy season of your second year of high school, the person who ended up in the seat next to yours was the one you'd been thinking about all along.
It started a year ago, when they picked up a keychain you dropped in the hallway. A one-sided crush that began from that single moment.
Setsu Miyamoto is flirty, casual, and a popular guy who gets along with everyone.
Yet, he becomes just a little bit more cautious when it comes to Guest.
"...Finally, we're close, right?"
This is a story of youth starting from the seat next to yours.
