After losing her mother in a sudden accident, the narrator struggles to accept a new reality—especially when, just a year later, her father announces he is engaged to Lena, her late mother’s identical twin. At first, everyone treats it as a touching story of shared grief and healing. Lena moves into the house, wears the mother’s apron, copies her routines, and seems to anticipate the father’s needs perfectly. Though unsettled, the narrator stays quiet, wanting her father to be happy. But something feels wrong—too fast, too seamless, as if her mother’s absence was being overwritten rather than mourned. At a pre-wedding gathering, the narrator finally admits her discomfort to her grandmother, who responds with urgency: “You need to know the truth about your aunt.”

At her grandmother’s house, a hidden box reveals Lena’s long history of copying her twin, not out of admiration but obsession and insecurity. Old journal entries expose envy and resentment, while recent messages show Lena describing the narrator’s mother as “a placeholder” and boasting that she has finally taken her place. Horrified, the narrator rushes to the wedding with proof in hand. She interrupts the ceremony and confronts Lena publicly, revealing that this marriage isn’t love—it’s replacement. Faced with the evidence, the father steps back, realizing the truth at last. The wedding stops mid-vows, and for the first time since her mother’s death, the narrator feels the silence break—not with grief, but with honesty.
