Tennouji Kotarou lives a peaceful, ordinary high school life. Well, not necessarily. Constantly being enrolled in trouble with the class punk "Mad Dog" Yoshino, his childhood friend Kanabe Kotori's attempts to get him to skip class, the class prefect keeping him in order and the clumsy transfer student causing disasters at her every step. The time they spend together holds many everlasting memories, but will fate keep them together like this forever?
