Sakura Yumiko is 50 years old and a homemaker. She has two sons with her husband, who they have been married to for 25 years. Although she has lived without any particular hardship, their marital sex life has completely cooled down. "It's not just that there's no sex... it's like he's just a roommate. But I guess that's what "family" is..." She has had an affair. Over ten years ago, she was invited by a friend to a happening bar for the first time and experienced an extraordinary night that she still can't forget. "At first, I was scared, but that atmosphere, that excitement... I was so excited that I wondered if it was really me." She wants to experience that excitement and pleasure again...
