Tsubaki lives with her husband, Takayuki, who works in sales. Because of her nervous and self-centered husband, she has a hard time staying at home. The only time she could find peace of mind was when her husband was at work, taking a relaxing bath. One day, Takayuki recommends his subordinate, Kanda, who soiled his suit due to carelessness during the outing, to use the bath at his home nearby. At the same time, while Tsubaki was taking a bath, Kanda ran into a scene where she was indulging in her masturbation to fill the loneliness of her not being dealt with by her husband.
