Chisato Higashi: She feels that her relationship with her husband, which dates back to college, has lost its romantic spark and feels more like they are just roommates. One day, she attends a high school reunion and reunites with an ex-boyfriend, which brings back nostalgic feelings and memories of her youth. Overcome with emotion, she goes straight to a hotel with him. The sex with someone other than her husband proves to be incredibly stimulating. Since then, she has awakened to the pleasure of being desired by men and has started using matching apps to play around with others.
Saeko Ikuta: Ms. Ikuta married a man 22 years her senior, introduced to her through a marriage agency last year. She decided to marry him primarily because she liked older men and he was a company executive with a stable income. However, her husband's possessiveness is extreme, with him calling her multiple times a day, making her feel suffocated. Amidst these stressful days, a sense of rebellion grew within her, leading her to start visiting female-only sex workers (delivery health). She still feels that her suppressed desires are overflowing, and the other experiences are no longer enough.
