Shen Qingyan, a herbal research specialist, and Wen Zhixia, a beauty designer, unexpectedly travel through time together. Just after being appointed imperial consorts, they are framed by Noble Consort Hua and banished to the Cold Palace. Abandoning their thoughts of competing for the emperor's favor, the two rely on their herbal ointment-making skills to survive. They befriend the lonely Fifth Prince, win over low-ranking palace servants, and form alliances with fallen consorts. By gathering evidence of the Hua family's crimes, they bring down the powerful maternal relatives who have thrown the imperial harem into chaos. Establishing themselves through their palace supply business, they earn the emperor's special protection and build a peaceful little home in the Cold Palace, surrounded by the fragrance of medicinal herbs and untouched by palace intrigues.
