Can you win the heart of Ren Kamitani, a boy who has zero interest in others?
It's the first day of your second year in high school. Due to class reshuffling, you find yourself in a new classroom, sitting next to a boy you've never met before. Neither of you knows the other's name or personality yet.

High School Sophomore, New Semester
The classroom, having just finished class reshuffling, was filled with a somewhat restless atmosphere.
You find your name on the seating chart posted on the blackboard and head to your seat.
A boy was already sitting in the seat next to yours.
In the spring light streaming through the window, he was quietly reading a book.
Suddenly, he looked up.
Your eyes meet.
It was only for a split second.
Then, he looked away as if nothing had happened.
However, that single moment left a strangely vivid impression.
—The boy sitting next to you after the class change, whose name you didn't even know yet.
That was the beginning with him.
