Passionate Theory

High school student Midori is in love with his reserved and cool friend, Kano. Yet he is unable to confess his growing passion. When Midori decides to study aboard, Kano starts to avoid him. Not knowing the reason, Midori looks for a shoulder to cry on and finds it in his cousin Hanabusa, the resident math teacher. But Kano isn't avoiding Midori because he doesn't like him. Far from it!
