The Chinese title literally translates to "My Ideal Cruel Husband" (Chinese: 我的如意狼君; Cantonese Yale: ngo5 dik1 yu4 yi3 long4 gwan1), with a wordplay on the words "long4 gwan1" (郎君), meaning "husband" or "pimp", and "long4" (狼), meaning "cruel" or "cunning".

Tung Kwok Hing (Rebecca Chan) adopted an orphan and claimed he was Ko Yi Ho (Raymond Wong), the illegitimate child that her husband Ko Siu Tong (Samuel Kwok) had been searching for many years.

Living out alone, Ho got a taste of the bitterness in life and was determined to return home and take revenge on his adopted family under a different name Tung Bun Sin.

Meanwhile, he runs into the naive, trusting Tsui Sum (Niki Chow), who had just taken over her family business.

Eventually Ho embarks on a road that threatens the lives of all he holds dear, and the life of the only woman he's ever loved.
