Yuko is supposed to take care of her father-in-law while her mother-in-law goes on a hot spring trip with a friend. She works hard to care for her, but her father-in-law, who has been aiming for Yuko's body for a long time, makes her sexually harassed. Sexual harassment becomes radical and has a relationship with the end without worrying about Yuko who is confused. Although he felt guilty about his husband and mother-in-law, he became a toy for his father-in-law.
