Marrying a concubine’s son? What a joke! She immediately arranged a marriage with a prince

Yu Jiaojiao, the eldest daughter of the Chengan Marquis, dies in agony three years after her wedding, having been poisoned and abandoned by her husband Jiang Peilang and her half-sister Yu Jingjing. In her final moments, she realizes that the marriage was a conspiracy to steal her dowry, and that she had been manipulated into swapping brides on her wedding day, missing her true match: Jiang Xingyan, the powerful but crippled Prince of Jing. Reborn to the moment before her wedding, Yu Jiaojiao resolves to change her fate. During the ceremony, when Jiang Peilang enters the bridal chamber expecting to claim his bride, Yu Jiaojiao reveals that she is wearing the phoenix-patterned wedding gown reserved for a princess, not a common noblewoman. She declares that she is the rightful bride of the Jing Prince, exposing the sedan chair swap and shaming Jiang Peilang in front of the gathered guests.

Jiang Peilang attempts to force the veil off, but Yu Jiaojiao defends herself with a hairpin and demands the presence of the Jing Prince. Jiang Xingyan arrives in his wheelchair, having come to retrieve his wife. In their previous life, he had left in anger after the mistake was discovered, but this time, Yu Jiaojiao accepts him immediately. She recognizes that despite his paralysis and rumored violent temper, he is the only ally who can protect her from her enemies. They return to the Wang residence and complete their wedding ceremony. Yu Jiaojiao examines Jiang Xingyan’s legs and discovers that his paralysis is not natural but the result of a rare poison. She vows to cure him, beginning a treatment regimen that includes medicinal baths and acupuncture.

On the morning after the wedding, Yu Jiaojiao faces hostility from her half-sister Yu Jingjing, who is now married to Jiang Peilang. Yu Jingjing attempts to undermine Yu Jiaojiao’s status by reminding the family matriarch of Yu Jiaojiao’s past infatuation with Jiang Peilang. However, the matriarch supports Yu Jiaojiao, enforcing strict etiquette and forcing Yu Jingjing to apologize. Later, Yu Peilang confronts Yu Jiaojiao in the garden, attempting to manipulate her with false affection. Yu Jiaojiao rejects him coldly, and Jiang Xingyan intervenes, forcing Jiang Peilang to kneel and apologize to his aunt. Jiang Xingyan’s protective behavior signals a shift in their relationship, as he begins to show genuine care for Yu Jiaojiao.

Yu Jiaojiao returns to her father’s mansion for the traditional visit after marriage, only to find her mother, Madam Yu, drugged and framed for adultery. The scene is staged by Concubine Su and Yu Jingjing to ruin Madam Yu’s reputation. Yu Jiaojiao uses her knowledge of medicine to identify the poison and employs a venomous snake trained by Jiang Xingyan to track the scent of the drug. The snake targets Yu Jingjing, exposing her involvement. Under pressure, Yu Jingjing implicates Concubine Su, who confesses to the crime out of jealousy for the Marquis’s favor. The Marquis, Yu Rencheng, punishes Concubine Su but remains biased, leading Yu Jiaojiao to confront her mother about her blind loyalty to a husband who would rather protect a concubine than his wife.

Following the incident, Yu Jiaojiao is invited to a banquet hosted by Princess Chang, a powerful noblewoman. Yu Jingjing, desperate to regain social standing, manipulates their mother into asking Yu Jiaojiao to bring her along. Yu Jiaojiao refuses, citing Yu Jingjing’s bad reputation and the risk to the family’s honor. Undeterred, Yu Jingjing’s brother, Yu Wenbo, devises a plan for her to sneak into the banquet disguised as a servant. At the event, Yu Jingjing attempts to spread rumors that Yu Jiaojiao mistreats the Jing Prince due to her past obsession with Jiang Peilang. Her scheme begins to unravel as the noble ladies listen intently to her gossip, setting the stage for further conflict as Yu Jiaojiao navigates the dangerous political and social landscape of the capital.
