This drama revolves around the marriage of Lu's children and tells the story of the marriage between five in-laws. One day, the nine people of three generations of the Lu family were preparing to take a family portrait, but unexpectedly a pair of strange men and women came to the house, claiming to be Lu's in-laws. It turned out that the second son Lu Qiwei married the company boss Yang Guang without telling his family, and the visitors were Yang's father and mother. Lu Wannian and Yu Chunlan strongly opposed their daughter's marriage, but after learning that Lu Qiwei was pregnant, they had to give up. Yang's mother wanted to have a grandson. After learning that Lu Qiwei's pregnancy was fake and that she wanted to get Yang's "private money" to start a company, she not only took her anger out on the Lu family, but also locked Lu Qiwei up at home. Lu Qiwei was determined to have his own career, so he ran away from home to start a company, which led to the escalation of the conflict between the Lu and Yang families. In order to let the eldest son Lu Qiyuan get married as soon as possible, Yu Chunlan asked his neighbor Li Guihua to matchmake for Lu Qiyuan. Lu Qiyuan swore not to marry in this life because of the failure of his first love, which led to a farce ending in blind dates again and again. Lu Qiyuan couldn't stand the entanglement of his colleague Lu Dagang and pretended to be Lu Dagang's girlfriend. Unexpectedly, Lu's father and mother believed it and went to Lu's house to propose marriage several times without telling Lu Qiyuan, but they met Lu's relatives and failed. The third child Lu Qihai and Li Guihua's daughter Li Liping are classmates. Because Lu Qihai is the only grandson of the Lu family, his marriage can be decided by the whole family, but not by himself; and Li Liping is the only daughter of the Li family, and her marriage can only be decided by her mother. The two people who couldn't make the decision on their marriage finally wanted to make a decision, so they fell in love unexpectedly. Yu Chunlan never dreamed that she and Li Guihua would become in-laws, and Lu Wannian never dreamed that the third daughter Lu Qixiao would fall in love with Huang Jiahui, the son of his factory director. With the help of Huang Jiahui, Lu Qiwei finally realized his dream and became a TV host. After several twists and turns, Lu Qixiao accepted Huang Jiahui's feelings, but Huang's father refused the marriage on the grounds that Lu Qixiao was beautiful.
