Housewife Chizuru (32) embarks on a one-night, two-day trip with a man she's just met. Married for three years, she and her husband are a dual-income couple without children. Her husband, three years her junior, first met her when he worked as a tutor in college, counseling a young man who had failed his exams—since then, he's warmly watched over his growth for twelve years. Though they respect each other and share a strong bond, behind their seemingly perfect life lies Chizuru's hidden struggles. With their home built using financial support from her parents, the pressure to produce grandchildren has intensified, weighing heavily on her. Amid this burden, her encounter with a new man opens a path she's never walked before.
