Description：Tachibana Akira (Nana Komatsu) is a 17-year-old female high school student. Unlike other girls of the same age, Tachibana Akira is calm beyond her age and a little indifferent. In her spare time, Tachibana Akira works part-time in a family restaurant. The store manager, Kondo Masaki (Yo Oizumi), is Tachibana Akira's boss. Masaki is a sloppy middle-aged man with a confused and somewhat natural personality, and he often makes Tachibana Akira blush and her heartbeat unintentionally. Yes, Tachibana Akira fell in love with this man who is more than 20 years older than her. Even though Masaki has been married and has a child, Tachibana Akira still can't resist his attraction, and Masaki seems to be unaware of his surging feelings for Tachibana Akira. Once upon a time, Tachibana Akira was the ace of the school's track and field team, but for unknown reasons, she chose to quit the team. After learning of this information, Masaki began to encourage Tachibana Akira to pick up running again.
