Song Yu, the eldest daughter of the Song Dynasty, and Song Jingxian, the adopted daughter, have complex roles in the feud between the prosperous Song Dynasty and the Song Dynasty. On the day of Song Yu's wedding, her fiancé Sheng Siyu was in a car accident and fell into a vegetative state. The ambitious Song Jingxian colluded with Gu Yiheng, a rival of the Sheng family, in an attempt to seize the two properties. Song Yu was forced to marry into the Sheng family. She was made difficult and provoked by the old lady of the Sheng family and Song Jingxian. She was also falsely accused of cheating and destroying her works. But she stunned everyone in the costume design competition with her "National Style Boy". Song Jingxian told the bombshell lie that Song Yu's mother was the mistress, and Assistant Qin exposed her conspiracy at the critical moment. The awakened Sheng Siyu also exposed Gu Yiheng's crimes and firmly protected Song Yu.
