Childhood best friends. Two halves of a whole. The cool, smart one who's good at almost everything, and his average, dorky friend who struggles to do anything right­—Yamato and Kakeru. Always by the other's side, but not together in the way they truly want to be. No matter how hard they try, their hearts cannot reach each other.

Toki-Kun is a yankee who gets into fights. But despite his appearance he is actually a gentle guy. He gains favor with Mr. Sahara, who is not only a physical education teacher but his homeroom teacher. The loud gong of a straight-gay unrequited love echoes out!!
