Shen Yuanshi, the eldest daughter of the Duke of Zhenguo, was tricked by her stepmother Liu and stepsister Shen Wanning in her previous life to marry into the East Palace and become the crown princess. On the wedding day, she was slandered for being unfaithful. After she was deposed in the cold palace, she was drunk with poisonous wine by her stepsisters and died out of hatred. Before she died, she saw Beishuo's protégé Pei Jin looking at her from a distance in the snowy night.
Reborn and returned to the night before her haircut, Shen Yuan's heart was as solid as stone. Relying on her past life memories and the "photographic memory" she gained after her rebirth, she worked step by step: she killed her stepmother during the ceremony, exposed the housekeeper's corruption, and teamed up with her brother Shen Yanqing, who was stationed at the border, to design a "private meeting" between her stepsister and the prince to be exposed, and successfully avoided the trap of the prince. She discovered that Pei Jin was also a reborn person, and the two formed an alliance to fight against Xiao Chenghao, the third prince behind the scenes. With the support of the eldest princess, the heroine entered the palace to play games. Her stepsister was ruined and her stepmother was divorced.
However, the truth is far crueler than imagined - the culprit who killed the heroine's grandfather and poisoned Pei Jin's biological mother was actually the current emperor. The heroine fakes her death and rushes to the frontier to help her brother repel the invading enemies of Beishuo; Pei Jin mobilizes the "Jin Pavilion" he secretly cultivated to cooperate internally and externally. In the final palace coup, the emperor was executed, Pei Jin returned to the country to regain the throne, and the heroine became the first female prime minister in Daliang. The two agreed to a three-year term, each to protect their homeland. Three years later, Pei Jin returned. In the heavy snow, plum blossoms filled the courtyard. They finally waited for each other.
