Rei Aino, 31, has been married for three years. Her husband works at a top-tier company, providing a comfortable lifestyle that allows her to stay home without working. Currently employed at a beauty salon, Rei is training hard to one day open her own ideal salon. However, her husband wants her to become a full-time housewife and start a family, conflicting with her ambitions for independence and career growth. This clash of desires has strained their marriage, leaving their intimate life nonexistent and stress building steadily. Recently, a coworker introduced her to the world of women's brothels, leading Rei to visit one for the first time.
