27-year-old Natsumi, triggered by a heartbreak, begins her journey into shame play. This documentary-style work portrays her gradual realization that the "wetting herself" and "incontinence" she once felt embarrassed about are actually sources of pleasure for her. To heal the pain of lost love, she confronts herself and experiences new discoveries and emotions. The act of holding in urine transforms into a new form of enjoyment, and her inner transformation is depicted in careful detail.
