Ayaka has been married to her husband for two years and her and her husband's married life is becoming more and more boring. The changeable nature of women makes Ayaka turn into an unfaithful woman. This was discovered by her middle-aged father-in-law who was living with her family. One day after Ayaka went to a motel with her boyfriend, her father-in-law waited at home and showed him a picture he took of the other man. The father-in-law seized this opportunity and wanted to force his love on his rich daughter-in-law Ayaka. Having no other choice, Ayaka's wife had to accept and please her father-in-law.
