Wang Qiming (Louis Koo) is a bank manager. He has no romantic cells. He actually took his girlfriend Annie (Gigi Leung) to queue up for hot pot on Valentine's Day, which made his girlfriend very angry and their relationship entered a freezing period. Wang Qiming found a love consultant Ouyang Xinjie (Charlene Choi) on the Internet, hoping to get her help to save his love with his girlfriend. When Qiming learned that Xinjie was a 19-year-old girl who had never been in love, he was deeply skeptical of her ability. Annie met two married men who were unable to develop a relationship. Then she met a business tycoon Victor (Donnie Yen), who was rich and knowledgeable, and proposed to Annie. Annie thought of her boyfriend and was in a dilemma. Qiming knew that his position was threatened. With the help of Xinjie, he looked for what he lacked. Qiming thought of his previous girlfriends and realized his mistake. The deadline for his appointment with his girlfriend came. They danced on the street and then turned away. Tears flowed down their faces, and they both decided to look back.
