Cao Lingxiao and Liu Lingshan have been close friends since childhood. His father is the director of the power supply station, and his mother works in the same company as Liu Lingshan's mother, serving as director of the logistics department. He also has a sister Cao Zhiruo who is 8 years younger than him. Ou Lingshan's father is the chairman of the guild of a state-owned enterprise, and her mother is the workshop director. The parents of the two families are very good friends. He has watched her grow up since he was a child. When he was a child, because he was 8 years older than Liu Lingshan and his sister, and because both parents were busy at work, transporting them to and from school every day became an indispensable job for him, and she became an indispensable little tail in his life. But when he grew up, he left her because he was admitted to a northern university and his parents were transferred to other places for work. When Liu Lingshan grew up, she also lost contact with her because she studied in pre-school education and worked in Shenzhen City after graduation. Many years later, during the Spring Festival, Cao Lingxiao returned to the mountain town because his parents missed their old friends (Liu Lingshan's parents) and inquired about her and her parents. At this time, the mountain town was no longer the town in Cao Lingxiao's memory. Instead, it was full of high-rise buildings. Liu Lingshan's family also moved to the city due to her parents' job transfer. Just when their family was disappointed, they met an old neighbor. After being informed by him, Cao Lingxiao finally got the new address of Liu Lingshan's family. Cao Lingxiao had no choice but to drive her parents to the city, and he knocked on her door. When Ou Lingshan opened the door and saw her eldest brother's family, she welcomed them warmly. And he silently looked at the lively and agile her, and the missing piece in his heart was finally found. At this point, he launched a plan to chase his wife.
