Yuzuki Aida, 35, a full-time housewife. After ten years of marriage and raising one child, she suddenly begins to feel a deep sense of unease in her relationship with her husband. Since childbirth, their sexual activity has noticeably declined, and she gradually starts harboring inner anxiety. Her husband often says, "Nothing in the house works without me," repeatedly emphasizing how dependent he is on her as a wife. Yet his words feel laden with obligation, making her feel more like a convenient caretaker than a desired woman. As her sense of self-worth as a wife erodes and her sexual needs remain unfulfilled, she reaches the milestone of her tenth wedding anniversary burdened with inner conflict and dissatisfaction, forced to reevaluate her identity. Amidst emotional loneliness, sexual frustration, and repressed desires, she faces a life-changing decision.
