The story revolves around four teens - the good-looking twins Yuuta and Yuuki Asaba, the effeminate Shun Matsuoka, and the class head Kaname Tsukahara - who have known each other since early childhood. While they are not necessarily good or bad friends, they continue to hang out well into high school. The half-Japanese transfer student Chizuru Tachibana joins the circle of friends in this comedy about the everyday life of adolescence.
