Follow the lives of four teenaged boys — the good-looking twins Yuta and Yuki Asaba, the effeminate Shun Matsuoka, and the class head Kaname Tsukahara — who have known each other for most of their lives. Their friendship has its ups and downs, but they remain close right into high school. A half-Japanese transfer student named Chizuru Tachibana joins their group and adds a new dynamic to the everyday adolescent friendships depicted in this comedic anime. (from ANN)
