In the 1920s of the Republic of China, the North and the South were divided. In name, the remaining etiquette of the previous dynasty still existed. The military and political tycoons in various places were intertwined with the old clan clans. The cities of Shanghai and Ningzhou were reveling in wealth, but in reality, power and money were traded everywhere. The Shen family, the oldest clan in Ningzhou, is in charge of textiles, banking, and shipping. Since their ancestors once gave birth to a "Queen", the family still has a phoenix crown and a queen seal, and regards the "Queen's bloodline" as the dignity that maintains the lintel. The upstart Gu family, which relied on military industry and armaments, is in urgent need of a decent marriage to clear their origins. The heroine is the nanny of her mother and her younger brother. She is forced to marry into the Gu family as the "Queen's direct lineage" and sign a three-year contract marriage with the Gu family's heir: she supports the Gu family's appearance and suppresses the wealthy clan members for him; he protects the Shen family's property for her and does not allow others to touch her family. But when the old accounts between the two families, the secrets of the previous dynasty, and a phoenix crown that can truly determine the interests of all parties surface at the same time, this clearly priced marriage gradually turns into a wealthy family wrestling and a game between men and women that no one can afford to lose.
