Shen Jinghong is a concubine from a declining aristocratic family. She was rejected by her family because of her humble biological mother and her upright temperament. When the marriage contract between the eldest sister and the powerful "Gongzi Zhao" changed, the Shen family, in order to preserve their reputation and interests, stunned Jinghong and forced her into a sedan chair to marry her. Gongzizhao is famous in various countries as a romantic playboy, but in fact he is a secretly cultivated heir of a powerful country. He didn't care about the political marriage at all, and he was full of contempt for the "abandoned daughter" who came to marry him. On her wedding night, Jinghong faced an indifferent husband and a complicated house. Instead of feeling sorry for herself, she calmly analyzed the situation. Using her keen insight into people's hearts and her pragmatic ability to adapt to local conditions, she first defused the servants' difficulties, and then used a novel "market economy" strategy to unexpectedly solve the food and salary crisis in her husband's fiefdom, showing his talent for the first time. Gongzizhao gradually noticed the difference in this "wrong" bride, and changed from indifference to curiosity, appreciation, and finally deep admiration. As they jointly dealt with a series of conspiracies from the royal family, aristocratic families, and foreign enemies, the two transformed from a contracted couple into allies and lovers sharing life and death. With his vision and structure that transcended the times, Jinghong not only reshaped his own destiny, but also deeply participated in and influenced her husband's path to the throne and the general trend of the world. Ultimately, it was proved that the original "mistake" was the most correct destiny arrangement.
