Karen says she has a good relationship with her husband. "We spend our days off together, and we even have sex." The reason she appeared on the show was because she wanted to experience a sense of immorality. She had a desire to do something naughty without her husband knowing, and six months ago she made a mistake with a former classmate she met at a class reunion. She says she still hasn't forgotten the sense of immorality she felt at that time. Furthermore, the image of Karen, who appears pure and innocent, crumbles as she recounts her obscene adultery.
