The film challenges the boundaries of traditional family ethics, revolving around the complex relationships within a blended family. It tells the story of a young woman who moves into her stepfather's home after her mother's remarriage. Under this seemingly calm but turbulent roof, the protagonist and her nominal "father" (stepfather) gradually blur the lines of seniority in their daily interactions. Fueled by the oppressive family atmosphere and her unfulfilled loneliness, a forbidden spark ignites, and the two cross moral boundaries, developing a deeply secretive and betrayally twisted physical relationship.
