Housewife Shiori (28 years old). Three years into her marriage, no children. As a full-time homemaker, her days are spent waiting for her husband who leaves early and returns late, passing time with baking and hobbies. Their relationship carries unresolved tensions—the 19-year age gap, her husband’s prior divorce, and her parents’ opposition—all taboo subjects never discussed, creating silent rifts between them. Seeking an escape, Shiori embarks on a two-day, one-night trip with a man she’s never met. Despite loving her husband, she surrenders herself to a stranger, searching for new emotions. On this journey, she opens her heart to an unknown man—a brief yet intense experience that frees her from the constraints of everyday life.
