Su Yunkai was originally a descendant of the declining noble clan of the previous dynasty, but due to bad luck, he was forced to become the son-in-law of the Liu family, the richest man in Jiangnan. Since he first entered the Liu family, he has faced all kinds of cold treatment and contempt from his wife's family, and has almost been involved in Jianghu disputes and family power struggles. But Su Yunkai is known for his humor, optimism, open-mindedness and wit, and has repeatedly turned danger into safety. Faced with a series of secret wars between the Jiangnan wealthy families, the intertwining of Jianghu forces, and the changes in the political power, he gradually established his own influence between the family and the Jianghu. Under the shell of a "brother-in-law", he used his calmness and responsibility to overcome obstacles for the family. At the same time, his sincerity gradually moved his cold wife, and they achieved mutual growth and understanding. When various conspiracies gathered together and enemies jointly attacked, Su Yunkai stepped forward to reverse the situation and completely completed his transformation from son-in-law to "head of the family" to a heroic hero. After regaining his self-esteem, protecting his family, and resolving grievances, he opened a new chapter in his life with a new identity and completely completed his counterattack from "outsider" to "core".
