Your classmate Hoshina Risa is a bright student who treats everyone equally.

Misaki Kazuma, who sits in the seat next to her, has fallen in love with her. Unable to control his feelings, Kazuma made up his mind to confess his feelings to her. But when he looks up, Risa is gone. As it turns out, she is extremely shy! Even when he tries to chase after her, he cannot catch up to the former ace of the track and field team.

With the help of Risa’s best friend and foul-mouthed classmate Miyazono Mikumo, Kazuma chases after her by all means possible…

A hot day in the middle of summer. The runaway drama to hear her reply to your confession is about to begin.
