An unexpected love quadrangle with a dash of unrequited love as two classmates, a boy and a girl, begin to fall for each other when each of their best friends have already fallen for them. Love is already hard enough, but it becomes an unnavigable maze for unassuming high school student Taichi Ichinose and his shy classmate Futaba Kuze when they begin to fall for each other after their same-sex best friends have already fallen for them. Toma gets seriously injured diving in front of a car to save Taichi, leaving Taichi racked with guilt over not just getting his best friend hurt, but also stealing his last chance at making the summer baseball tournament.

Guilty and angry, the two boys clash in an emotionally raw argument. Futaba, worried about both of them, invites Taichi out in an attempt to cheer him up.
