Jiang Shiyuan, the daughter of the general who ruled the country, was humiliated by Shen Luchu, whom she had a crush on for ten years. In order to help her cousin seize the heirloom, she took the initiative to marry into the Pei family in the capital, but mistakenly made a marriage contract with Taifu Pei Che as a playboy, Pei Ziye. After her marriage, she gradually came to know Pei Che's gentleness under his coldness, and the two worked together to resolve palace intrigues, family disputes, and foreign enemy conspiracies. Shen Luchu regretted it but resorted to despicable means to save the relationship, completely severing the relationship. Jiang Shiyuan relied on his wisdom to take charge of the family and broke the situation with incense. Pei Che cleared the obstacles for her. The two moved from wrong fate to the same heart, and finally protected their family, country and each other in the whirlpool of power.
