Male protagonist: Ning Ruian, titled Prince Ning, the sixth son of the emperor. On the surface, he is romantic and casual, but in fact he is thoughtful and strategic. Because his mother and concubine died young and his wife's family is weak, she hides her edge and accumulates strength secretly for self-protection. He is good at power planning, understands people's hearts, attaches great importance to love and justice, and has the ambition of being a wise king.
Female protagonist: Huahua (whose real name is Hua Hua and nickname Huahua) is an orphan girl who was born in the market.

Toughness and survival wisdom are honed in the marketplace.
Background of the era: In an imaginary dynasty (such as the Yin Dynasty), the struggle for imperial power is fierce, there are many factions in the court, and there may be hidden dangers on the border.
