God-Given Happy Enemies

In the middle of the Ming Dynasty, plague broke out in Cenjiazhuang and pests were rampant. The villagers fled to death. Helpless, Cen Huanxi, who had no martial arts skills, had no choice but to take his family's girl Wuer north to look for relatives. His father, Cen Dazhuang, is a pig butcher in the capital. He is an outspoken and honest person. Originally, Cen Huanxi came to seek refuge with his father just because of the pressure of life. Who would have thought that enemies would not get together. On the first day after Cen Huanxi entered the capital, he met Song Shijun, the suave and cynical richest man in the capital, because of a festival. Cen Huanxi, who has a bold personality, looks down on Song Shijun, who is bohemian and rude. Song Shijun even looks down on Cen Huanxi, who behaves vulgarly and has a loud voice. The two people who hate each other thought that each other's lives had nothing to do with each other and had no intersection. When they met for the first time, they made the harsh words "We will never see each other again until we die." Unexpectedly, within a few days, Song Shijun's benefactor Cen Dazhuang and his daughter were involved in a murder case due to an adulterer. Cen Dazhuang, who was eager to protect his daughter, was worried that his daughter would be implicated because of him, so he had to ask Song Shijun, who had always had some friendship with him, to save his daughter. However, Song Shijun thought about it and found that there was only one way to save his benefactor's daughter and savior from the fire and water, and that was to pretend that Nacen was happy to be his third wife and make the benefactor his father-in-law. Faced with Song Shijun's "tricky and mean" request, should Cen Huanxi accept or refuse? What kind of "bloody" sparks will the two create in the future?
