Married woman Mutsumi (36) embarks on a two-day, one-night trip with a man she's just met, an encounter that becomes a major turning point in her life. Three years into her marriage, she works as a caregiving massage therapist, finding fulfillment despite the challenges of balancing work and home life. Visiting elderly clients and nursing homes, her job is physically demanding—six months prior, she fell ill and was forced to take a leave of absence. Recently recovered and ready to return to work, her husband urges her: "Quit your job and let's have a child." Though she feels love for her husband's concern, his words deepen her inner conflict. While she's always hoped to have children someday, she knows her age makes it difficult. Yet she still wants to continue working. Torn between her career and her marriage, she sets off on this journey in search of an answer.
