The Dayin Dynasty was established for a hundred years, but the imperial power declined and the vassal kings were divided. There are constant wars on the border, secret intrigues in the court, and aristocratic families from all over the country are fighting openly and secretly. The world is divided and united, and the undercurrent is surging. In the capital, Shen Zhiyi, the legitimate daughter of the Prime Minister's Palace, was smart and eloquent since she was a child. Due to a family marriage, she was forced to marry the cold-faced prince Xiao Chenyuan who guarded the northern border. This man has great military exploits, but he has a cold temperament and is not close to women. He lives on the border all year round. It is rumored by the government and the public that he has a heart of stone and is not moved by emotion. The two had no contact with each other before their marriage. They were married by an imperial edict and became husband and wife. In the deep courtyard of the palace, under the cold moon and high walls, the two of them went from being wary of each other to tempting confrontations, from misunderstandings to secret feelings, but they were repeatedly pulled apart by their positions, plots, and old grudges. They couldn't love each other, and they couldn't let go of hate. The dynasty is changing, and the rise and fall of the family are closely linked. A marriage that started as a contract has evolved into the most passionate and forbearing relationship in troubled times. The world and lovers, machinations and sincerity, in this chess game, no one can escape intact.
