Song Chuyu, the Anguo County Princess, experiences a profound rebirth that returns her to her youth at the moment her future husband, Kang Rui, achieves the title of Number One Scholar. In her previous life, she had married Kang Rui despite his humble origins, supporting his rise from a low-ranking official to a powerful minister. She believed their marriage was built on mutual devotion, especially after he risked his reputation to save her disgraced brothers. However, she later discovered that Kang Rui had concealed a prior marriage and a son, Qin Lianxiu and Kang Sixian, whom he had raised as his own sister-in-law and nephew within her household. Her brothers had colluded with Kang Rui, selling Song Chuyu into the marriage as a bargaining chip to secure their own futures. Betrayed and trapped in a loveless, deceptive union, she spent her final years as a recluse in a Buddhist temple, watching Kang Rui perform acts of devotion that were revealed to be hollow performances for political gain.
Upon waking in her sixteen-year-old body, Song Chuyu resolves to sever all ties with Kang Rui. She coldly observes the celebrations of his success, recognizing the man who would become her tormentor. Her path diverges when she encounters Lin Qingyuan, a destitute young man living in the slums of Shangjing City. Lin Qingyuan is a figure from her past life, a man of immense talent and ruthless capability who rose from peasant stock to become a warlord controlling the southern rivers. Though he saved the dynasty from collapse and was revered by history, he was despised by the noble elite of the capital for his methods and low birth. He died young, poisoned and isolated, while the court he protected continued to scorn him.
Song Chuyu witnesses Lin Qingyuan orchestrating a scandal in the imperial examinations to secure a position for his ally, Cao Zhao, demonstrating his strategic brilliance despite his current poverty. She also sees him compose a poem at the Autumn Frost Banquet, which she recognizes as his work. When Lin Qingyuan is brutally ambushed in the western district, Song Chuyu intervenes, saving his life and nursing him back to health at her private villa. This act of rescue marks a turning point. She realizes that in her previous life, she had never acknowledged Lin Qingyuan's contributions, allowing him to walk a lonely, tragic path while the nobility enjoyed the peace he secured.
Determined to alter fate, Song Chuyu confronts her mother and then the Empress Dowager, her aunt. She declares her intention to marry Lin Qingyuan, a man of servant status, defying all social conventions. When questioned, she reveals her ambition not merely to marry for love, but to enter the political sphere to protect him and ensure he receives the glory and recognition he was denied. The Empress Dowager, surprised by her niece's newfound resolve and political awareness, agrees to let Song Chuyu present Lin Qingyuan to her. Song Chuyu then approaches Lin Qingyuan, who is recovering from his injuries, and proposes marriage. She offers him a partnership, acknowledging his worth and promising to walk the path of power alongside him so he may live without the burdens of his former isolation. Lin Qingyuan, initially skeptical and wary of her noble status, ultimately agrees to the arrangement, seeing an opportunity to seize a chance at a different destiny.
