A beautiful lolita girl named Hitomi, who has never been able to overcome her childhood habit of wetting herself and had nearly given up on life, meets her uncle who is deeply attracted to her incontinence. The uncle exerts strong dominance over Hitomi, making her believe that she is loved only when she wets herself. This twisted affection gives Hitomi a new sense of hope. However, the uncle begins treating her like a toy, and Hitomi obediently submits. He mixes diuretics into her tea, forcing her to wet herself repeatedly, subjecting her to ongoing humiliation and suffering. One day, Hitomi experiences even more extreme shame. She is made to wear diapers and urinate on command, treated like a gothic lolita doll and used as her uncle's personal plaything in various degrading scenarios. Amidst it all, Hitomi begins to feel a strange emotion—believing that even as she loses herself, she is still unconditionally loved.
