A married woman named Miho Sanzono, age 32, with one child. She has a natural tendency to serve others, often putting their needs before her own. However, this trait has led to her husband becoming increasingly demanding and selfish, resulting in him taking control during their intimate moments. As she struggles with these changes, she begins to harbor feelings of resentment towards being treated like his servant. Despite never having engaged in infidelity before, she finds herself yearning for experiences outside of her marriage. In her words, "It's embarrassing to say, but... because I have an M-type personality, I just want to be used more..." Her pent-up sexual desires and hidden abnormal fantasies push open the door to the unconventional world of a pure, beautiful housewife.
