A century-old fujoshi unexpectedly transmigrates into the body of An Wuyang, the spoiled young lady of Yun City in the matriarchal nation of Fengyi, where women rule and men are subordinate. Initially thinking she could enjoy a life of luxury surrounded by handsome men, she instead finds herself in the middle of a murder plot orchestrated by her own husband. Armed with knowledge of the story, An Wuyang uses her foresight to avoid the trap and begins a plan to win over the hearts of the men around her, each with their own unique personalities.
An Wuyang outsmarts her scheming younger sister, An Yunchu, but is framed for the murder of their mother. Forced to flee with her husband, they become separated, and An Wuyang unexpectedly meets the foreign Saint Zhu Zhi, uncovering An Yunchu's years of betrayal and corruption within the family.
Learning that An Yunchu will stop at nothing to seize control of the family, An Wuyang teams up with the Saint, conceals her identity, and works with her husband to expose An Yunchu's true nature, breaking her psychologically.
The truth about the matricide is revealed, and An Wuyang's innocence is proven to the world. Along the way, her husband's initial intent to harm her gradually softens, and An Yunchu faces the consequences of her actions. An Wuyang reforms the An family, spreading the idea of equality for all, and grants her husband his freedom, ready to live a comfortable life on her own.
However, her husband arrives dressed in red to propose to her. Unwilling to commit, An Wuyang flees, only to find herself suddenly transported back to the scene of the murder plot, but this time, in a world where men rule and women are subordinate.
