27-year-old Sayu married her current husband due to family circumstances after graduating from university. With little experience in the working world, she was unable to marry the person she loved and has since lived as a full-time housewife. In reality, she and her husband are a paper marriage; while he's away, she freely goes out for lunch or attends hobby classes, living without any apparent restrictions. However, a deep, unshakable loneliness gradually builds inside her, leading her to seek comfort somewhere—anywhere. That's when she learns about women's brothels. Realizing her husband is unlikely to notice her absence during the day, she decides to take her first step in life driven purely by her own will. This story captures Sayu's emotional transformation and the warmth she so desperately seeks.
