Ayako Inoue (46) is troubled by her sexless life. The trigger was her inability to have children. Without properly investigating, the two gave up. Ten years have passed since then. She and her husband can't even have sex, not even kiss. Every day, she accumulates sexual dissatisfaction and a sense of emptiness, and now she even starts to fantasize about being assaulted by a deliveryman. ...Her husband is very gentle. This only makes it more painful. So Ayako contacted a man from her past. A man from 20 years ago... her past affair partner.
