Arisa (Kanna Misaki), who grew up in a single-mother household, lives with her mother, Michiko (Ayako Kano). Her mother works at a supermarket checkout during the day and at a snack bar at night to support her household. One day, her mother, drunk at work, comes home with a man. The figure of her mother's woman who she sees for the first time. And the existence of a man she meets for the first time... Her mother soon remarried the man of that day, Osamu Sakai. The awkward life of the three began. For adolescent Arisa, the casual father-in-law's behavior stirs the depths of her body as she begins to wake up. In her heart, she should have hated her father-in-law, but for some reason she wants the smell of a man.
