Plot
Hong Haoren, Zhu Guorong, and Liu A-Kun are good friends, all facing their own love problems.

Haoren is a white-collar worker, married to Min Hui, a successful executive and career woman who focuses her energy on her career more than maintaining her marriage.

Guorong is an Ah Beng car salesman, whose wife has gotten fat after having 3 kids. Looking for cheap thrills, Guorong cheats on her constantly, and uses the pretext of mobilisation to have one-night flings.

A-Kun is a 30-something virgin, addicted to pornography, who works as a provision shop assistant. His demanding boss' daughter has a crush on him, unknown to A-Kun.
