The story is set in an imaginary ancient dynasty - the Sheng Yuan Dynasty. This is an era that is prosperous on the surface but full of internal contradictions. In the court, foreign relatives and powerful ministers compete for power, and there are constant factional fights in the court. In the rivers and lakes, there are many sects, and conflicts often occur in order to compete for resources and territory. In this era, feudal ethics are strict, marriages are often dominated by political interests, and the love between men and women often struggles to move forward under the weight of family honor, national interests, and moral ethics.
