The story delves into the inner world of married woman Chizuru (32). In her third year of marriage, she and her husband are a dual-income couple without children. Her husband, three years her junior, began dating her after meeting as a tutor in college—he had counseled a young man who failed his entrance exams, and their relationship gradually developed. Twelve years have passed since, and they've grown together as a couple, supporting each other's growth. Their relationship, built on mutual respect, seemed perfect and smooth—until recently, when Chizuru's inner struggles began to deepen. After building a home with financial help from her parents, the pressure to fulfill the next generation's expectations has become overwhelming. Unable to bear the burden, she escapes reality by embarking on a two-day, one-night trip with a complete stranger—someone other than her husband. By the journey's end, she is passionately embraced and writhes in ecstasy in the arms of this unfamiliar man. This is the story of a married woman's hidden desires, anxieties, and a journey to rediscover herself.
