Jiang Yunrao, a modern dancer, unexpectedly travels through time and becomes an unfavored seventh-rank palace lady in the harem of Emperor Tianqi of the Great Zhou dynasty. Because her family backed the losing side in a political struggle years ago, she initially plans to simply coast through life. However, the palace runs desperately short of heating charcoal during the winter, forcing her to find a way to survive. While dancing on a snowy night, she unexpectedly encounters Pei Yan. Seeing her miserable circumstances, Pei Yan severely punishes the Imperial Household Department and promotes her two ranks at once. Her sudden rise in status makes Jiang Yunrao the target of jealousy throughout the imperial harem. Well-versed in the art of getting along with others, she moves to the secluded Yaohua Palace and relies on medicinal cuisine and mahjong to befriend the other consorts and live peacefully. Unexpectedly, her candid and carefree nature gradually wins Pei Yan's heart, and the emperor's wholehearted affection quietly begins to blossom.
