This story takes place in Hong Kong in the 1950s and 1960s. Deng Weixiang (played by Roger Kwok) follows his mother's will and comes to Hong Kong from the mainland to seek refuge with his future father-in-law, Ling Xingbo (played by Chin Huang). Unexpectedly, he fails to find Bo, so he first finds his cousin Deng Jingchen (played by Ma Guoming) to seek refuge with. Chen is a well-connected broker, who works hard all day and lives from day to day. By chance, Chen learns from a missing person advertisement that Xiang's future father-in-law is actually a wealthy businessman, Bo. Chen borrows money from the loan shark Lei Guili and teaches Xiang to lie that he has money, so they go to meet his future father-in-law together. Unexpectedly, Bo's wife, Lin Lanqing (played by Lu Wanyan), believes that Xiang is deliberately making trouble, and drives Xiang and Chen away. Xiang misunderstands that Ling despises his poor family, and his self-esteem is damaged, so he leaves in anger. Lei came to collect the debt. Cheung said that he was the cause of the incident and decided to pay off Chen's debt. Chen was moved, so the two cousins worked together to make a living. Cheung's roommate Zheng Biyun (played by Myolie Wu) and her brother Zheng Xiaolong (played by Lam Wing-tung) depended on each other for survival. Yun originally worked at Bo's floral water factory, but the factory manager took revenge on her and dismissed Yun. Yun had no choice but to temporarily work as a waitress in a dance hall. On the other hand, Cheung's fiancée Ling Feng (played by Kong Zhini) ran away from home because she didn't want her parents to arrange her marriage. Nanny Li Wendi (played by Xia Ping) arranged for Feng to live in a cubicle temporarily, and she became a roommate with Cheung and others. Feng developed a good impression of Cheung. Chen was also attracted by Feng's youth and beauty. Cheung gave Chen a token to pawn to pay off the debt in an emergency. He met Bo by chance. Bo recognized the token and mistakenly thought Chen was his future son-in-law. Qing's godson Xie Junmin (played by Lai Yiu-cheung) suggests to ask his "cousin" Di Lina (played by Huang Xingtong) to pretend to be Feng in order to deal with and test Chen. Chen is attracted by Na's beauty. After Yun quits her job at the dance hall, she goes to Da Da Di to sing for money. Because of her funny appearance and pleasant voice, she is very popular with the patrons. With the introduction of Nanyang tycoon Lu Gong (played by Li Chengchang), she is able to transfer to the karaoke bar to sing. Xiang even gives Yun a new song he composed for trial singing. Who knows that Yun is very popular. Xiang and Yun have similar interests and their relationship progresses greatly. After Chen learns that Na is also an imposter, he learns that Xiang's fiancée is Feng, and he can't help but feel mixed with surprise. Xiang is fired from the film set and comes to work at the Bozhi Flower Water Factory. In order to win Xiang's favor, Feng follows Xiang to work in the factory opened by his father. On the other hand, in order to avoid being exposed, Feng has to avoid Mian's father and factory director Xie Luquan (played by Peter Lai) from time to time, which is full of dangers. When Bo found out that the profit of the flower water factory dropped sharply, Bo decided to ask Chen to investigate on his behalf. Chuen learned that Chen was the "imperial envoy" and tried his best to curry favor with him, while hiding his own evidence. Chuen failed to embezzle public funds and was eventually fired, but Feng's true identity was also revealed. Xiang was furious when he learned the truth, and Chen insisted that he pretended to be Xiang because he was deeply in love with Feng. Feng was overjoyed to learn that her real fiancé was Xiang. Yun was shocked to learn that Xiang already had a fiancée and was heartbroken. Mian was afraid that Feng would really marry Xiang and ruin her big plan, so she used Na to seduce Xiang, but her ambiguous relationship with Na was exposed. Qing learned that Mian helped Po to keep a mistress in his mansion, and drove Mian away in anger. Mian and Quan hold a grudge and turn to the rival floral water company, stealing a lot of Bo's business. Xiang and Chen help save the situation. Suddenly, they have an idea and they play the role of "Sister Ma" and become the special trademark of floral water. They become popular among thousands of Ma sisters in Hong Kong and increase the sales of Bo's floral water. Fung confronts Yun and tells her that Yun's being with Xiang will only affect Xiang's bright future. Yun is willing to withdraw because she loves Xiang and pretends to be in love with the wealthy businessman from Nanyang who has been pursuing her, which makes Xiang give up. At this time, Long is diagnosed with acute heart disease and needs a large sum of money for surgery. Yun is eager to save Long and decides to marry Gong. In order to prevent Yun from ruining her lifelong happiness, Xiang resolutely agrees to marry Fung and borrows a large sum of money from Bo for Long's surgery. At this time, the floral water factory is facing financial difficulties again. Chen suggests sending a beautiful woman to represent the floral water in the Miss Hong Kong Exhibition. If she wins, it will definitely be a great advertisement. Yun agrees to represent Bo's floral water factory in the election. Quan and Mian harbored a grudge and revealed to the public that Yun had been a dancer. Xiang encouraged Yun to come forward and admitted that he was only forced by the situation that day. As a result, Yun won the Miss Industrial Exhibition election. Yun helped Xiang to save the floral water factory from crisis. As Xiang and Feng's wedding was imminent, he decided to withdraw and lied that he was not interested in the entertainment industry and decided to follow Gong to marry in Nanyang. Although Xiang was greatly shocked. On the wedding night, Xiang promised Feng that he would love Feng with all his heart from then on. Feng knew that Xiang and Yun were really in love and understood that love is not possession, so she told the truth. Xiang was able to rush to the dock in time to chase Yun back, and the lovers finally got married. Xiang was noticed for the floral water advertising song he made, and was able to enter the music scene and form a unique couple with Yun. Chen decided to be down-to-earth and start from the bottom of the factory to prove his sincerity to Feng, and Feng also agreed to give Chen a chance.
