After being dumped by his girlfriend, Iijima (a tutor) is confessed to by his shy student Daisuke. The incident takes Iijima by surprise... and it also makes him realize that he's gay. But the 5-year age difference and his position as Daisuke's tutor makes Iijima reluctant to accept Daisuke's confession. However, Daisuke doesn't care about their differences and, despite his shyness, is determined to win Iijima over.
