Married woman Tomoko (37 years old). In her third year of marriage, feeling uncertain about her relationship with her husband, she plans a two-day, one-night trip in hopes of changing herself. To overcome her distrust of men, she attempts intimate contact with a man for the first time. In high school, she was a victim of stalking, and since then has avoided relationships with men. Raised in a single-mother household, she had almost no opportunity to interact with men during her childhood. As a result, her first romance didn't happen until she was 27, and that initial encounter, lacking knowledge and experience, was painful. However, introduced by a friend, she gradually opened her heart to her three-years-older, serious and kind husband, eventually marrying after a year-long relationship. Still, days filled with dissatisfaction and anxiety in her marriage continue. Seeking personal transformation, she embarks on a journey in search of her first encounter with another man. Facing her fears and inexperience, yet summoning the courage to take that first step, she is embraced by a man for the first time, gradually freeing both her heart and body.
