In her previous life, Shen Yuanshi, the legitimate eldest daughter of the Duke of Zhenguo's household, was set up by her stepmother, Madam Liu, and stepsister, Shen Wanning. She married into the Eastern Palace as the Crown Princess, but on her wedding day she was falsely accused of infidelity. After being deposed and confined to the Cold Palace, she was forced to drink poisoned wine by her stepsister and died full of hatred. Before she died, she saw Pei Jin, a hostage from Beishuo, watching her from afar in the snowy night.
Reborn on the eve of her coming-of-age ceremony, Shen Yuanshi's heart turned to iron. Armed with her memories of her previous life and the ability to remember anything at a glance, which she gained after being reborn, she moved carefully at every turn. At her coming-of-age ceremony, she turned the tables on her stepmother's schemes. She exposed the steward's embezzlement and joined forces with her elder brother, Shen Yanqing, who guarded the border. Then she arranged for her stepsister's secret meeting with the Crown Prince to be exposed, successfully avoiding the trap of becoming Crown Princess. She discovered that Pei Jin had also been reborn, and the two formed an alliance to fight the mastermind behind it all, the Third Prince, Xiao Chenghao. With the support of the Grand Princess, the heroine entered the palace to contend for power. Her stepsister was ruined, and her stepmother was divorced.
Yet the truth was far crueler than she had imagined: the person who killed the heroine's grandfather and poisoned Pei Jin's mother was none other than the reigning emperor. The heroine faked her death and went to the border, helping her brother repel the invading forces of Beishuo. Pei Jin deployed his secretly built Jin Pavilion to coordinate the attack from within and without. In the final palace coup, the emperor was executed, Pei Jin returned to his homeland and reclaimed the throne, and the heroine became the first female chancellor of Daliang. The two agreed to spend three years apart, each guarding their own homeland. Three years later, Pei Jin returned. In the falling snow, plum blossoms filled the courtyard, and at last, they were reunited.
