Kozue Ogawa (Esumi Makiko) is a housewife and has been married to Hideo (Yanagiba Toshiro) for seven years. They don't have any children but as they live with her parents at their flower shop, everyday is still lively. She is happy with her life and her husband but she wonders if it is enough. From time to time, she is gripped by this doubt that she cannot raise with anyone. Kozue starts a part-time job in the editing department of the magazine where she used to work. Her former colleague is now working hard as the editor-in-chief. One rainy day, Kozue meets a young man. He is Takuma Fukazawa (Yamashita Tomohisa), a high school student. He seems somehow shrouded in sadness. He is a dance teacher. In the dance studio, there is just the two of them. Takuma curls his hands around Kozue's body and his dance instruction begins. Their unexpected closeness causes Kozue to hesitate. With her heart pounding, she pushes Takuma's hands away and runs home. But the throbbing in her chest continues. It can't be. But what is this feeling?
