Sex counselor Mok Tai Hung and sex therapist Lam Ching Yee have been dating for five years. The two love each other very much and want to take their relationship to the next step by getting married. But Ching Yee's strict and conservative mother Liu Doi Lam, is highly against them being together due to Tai Hung's financial status, him being a bit older than her daughter and also him having a son from a previous relationship.
