Ayaka lives with her husband, Takayuki, who works in construction. Her nervous husband is always on his toes, and he doesn't let his guard down even at home. Her only comfort was when her husband took a relaxing bath while she was at work. One day, worried about her boss, Kanda, who got dirty in her field work, Takayuki recommends that she use the bath at her home nearby. At the same time, while Ayaka was taking a bath, Kanda ran into a scene where she was indulging in her masturbation to fill her loneliness that was not dealt with by her husband.
