Shen Qingtang, the legitimate daughter of the Prime Minister's Palace, was framed by her stepmother and was forced to marry into the East Palace in the name of "Kefu". She married the seriously injured and comatose prince Xiao Jingheng. She relied on the medical skills left behind by her mother to revive the prince, but was despised by everyone in the Eastern Palace because of her identity. Faced with the difficulties faced by the concubine Su, the suspicion of the Queen Mother, and the cold treatment of the palace people, Shen Qingtang did not compromise - she used acupuncture to cure the Queen Mother's strange poison, saw through Su's fake pregnancy conspiracy, helped the prince find out the truth about the assassination, and gradually gained a foothold in the East Palace. From being cold and suspicious at first, the prince Xiao Jingheng was attracted by her tenacity and wisdom. The two of them gradually developed from a "couple in name only" to a "sympathetic" partner. In the end, Shen Qingtang helped the prince put down the prince's rebellion, ascended to the throne, and became the empress of the world, achieving a counterattack from a happy bride to the mother of a country.
