In her second year of marriage, Keiko is a housewife who feels a quiet sense of dissatisfaction despite having no major issues with her husband. Once, living together brought her joy and made each day exciting. Lately, however, she has started wishing for some distance between them. They have sex only about once a month, and even then, it doesn't happen naturally or passionately. As days pass at home, she feels she's gradually losing her sense of self, growing quietly anxious. Though she wants to make a change, she hasn't found the right opportunity or courage yet. Caught up in the routine of daily life, she struggles to find time to reflect on her own emotions.
