ku tse-keung (johnson lee) is an absentee father who boasts to his son, ku tui-nam (marcus lo), his busy life because of his important business meetings and huge deal making. however, tse-keung is really just an ordinary real-estate agent who cares more about work than spending time with his son. his work is so important to him that he would rather cancel his parental visits with tui-nam and use his personal time to socialize with his boss. tse-keung's inability to keep promises to his son has left him in a strained relationship with his ex-wife and her fiancé who have to make excuses to spare tui-nam from disappointment. when his ex-wife leaves hong kong to get married and go on a honeymoon, tui-nam is left in tse-keung's care for an extended period of time. jealous that his son is growing closer to his new step-father, tse-keung takes the task of being a responsible father seriously. however, not being used to taking care of his son has left tse-keung often overlooking his son's needs and feelings.
