Shen Qingdai, a draftsman at the Modern Design Institute, died suddenly due to overtime work and traveled to the Dajing Palace as a maid in the clothes bureau. At the beginning, she mistakenly broke into the royal study and disturbed the emperor. However, she was accidentally transferred to the Shangshi Bureau by Emperor Xiao Jingyuan because she bore a certain resemblance to Princess Zhaoyang who died young.
She improved her diet with modern knowledge, and won the favor of the Queen Mother and the Emperor successively, and was gradually promoted from a talented person to a noble concubine. Deep in the palace, she encounters the plot of the original heroine Su Qingyao, the noble concubine's difficulties, and is even involved in the conspiracy of the second prince to seize power - the frame-up of Concubine Xian's miscarriage, the secret cause of Princess Zhaoyang's death revealed by her old lady Zhao, everything pushes her to the forefront.
Although Xiao Jinyuan was obsessed with the "White Moonlight" Princess Zhaoyang, he gradually fell in love with Shen Qingdai, and turned from "substitute projection" to sincere treatment of each other. The two fought side by side in secret fights in the harem and disputes in the court. Shen Qingdai also grew up from a little palace maid who relied on the emperor to the backbone of the harem who could take charge of the rites on her own.
This pair of imperial concubines, who had gone through many tests, finally ushered in their stable springtime under the willows of the palace wall, and wrote a period of sober and sinking love in the palace.
