Two young girls who were mistakenly carried for eighteen years due to a careless delivery started their misplaced lives at the wedding reception. Qin Fuzhi, who lived a repressed life under the strict ethics of aristocratic families, returned to the farm to find freedom as he wished; Meng Jingchun, who grew up in the countryside, entered a high school, but felt tortured by rigid discipline. From the initial estrangement and confrontation, the two finally worked together to expose the conspiracy of the clan elders. The two families solved the knot in the past, and the two girls also broke free from the shackles of their identities and gained stability and warmth.
