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.
It's the last year of high school, and love is in the air. Romantic feelings that have been building up over years of friendship come to light. When Taichi's classmate Futaba asks him to help her confess to his best friend, Toma, it sparks the catalyst that begins the sweet and heart-wrenching journey of their third and final year of high school.
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.
