People's attitudes towards extramarital affairs can be seen from the following terms: Adultery - third party - extramarital affair. The term "adultery" not only carries a distinct derogatory connotation but was also regarded as a criminal act during a certain period. The term "extramarital affair" is clearly a neutral one, and it may even be talked about with relish by some people due to some special overtones. The consequences of an extramarital affair are basically two: one is to break the current combination and move on to a new one; The second is to retreat after going wild, quarrelling and making a fuss. Most of the extramarital affairs of urban white-collar workers choose the latter. They only want the thrill of extramarital love but are too lazy to get divorced. After Jian and Ping got married, their relationship has always been very stable. Their friends all envy their fairy-like life. But not long after, Ping discovered that her husband had another woman. Despite this, Jian's attitude and enthusiasm towards Ping did not change significantly, nor did he ask for a divorce. Ping considers herself a gentle and family-oriented wife, but she always can't figure out exactly what she has done wrong and where she has gone wrong. In a heart-to-heart talk with his husband, he said that he was looking for a lover not because his relationship with his wife had broken down, but merely because he was tired of the increasingly dull marital life and wanted to find some new excitement outside of his wife, "adding some salt, some vinegar, and some sesame oil to the plain life."

Due to the openness of social concepts, modern people's self-awareness is becoming increasingly strong. Whether men or women, many have begun to have higher requirements for the quality of their sexual life. One of the main reasons why modern urban white-collar workers tend to have extramarital affairs is that sex in marriage becomes monotonous and dull.

Modern emotional and sexual ethics also provide certain ethical grounds for extramarital affairs. In the film "The Third Party", the wife is confronted with an awkward logical reasoning: when it comes to marriage, the lover is undoubtedly the third party. When it comes to love, the wife has become an undoubted third party. This ethical concept that prioritizes feelings and emotions allows some people to use the guise of pursuing love to chase after love and sex outside of marriage.
