Anzu goes to a kindergarten with her friends, the shy Koume and the eccentric Hiiragi. Together they try to attract attention from their caretaker Tsuchida Naozumi. However, he is clearly more interested in the pretty Yamamoto Nanako, a fellow kindergarten teacher who supervises the class next door. Though Anzu tries to convince Tsuchida to marry her when she grows up, Tsuchida is trying to have a date with Yamamoto; or if not, get engaged with her.
