A father-in-law who fell in love with his son's wife, Kana, who should never be interested. The father-in-law observes Kana's private life and makes her delusions. I also peeked at sex and masturbation with his son. One day, my father-in-law who looked into the masturbation figure was called out to Kana. "Dad, I knew you were watching me all the time." However, Kana invited her father instead of getting angry.
