Ju'er, an orphan from the south of the Yangtze River, entered the palace as a maid. Because her features and eyes resembled the late emperor's favorite concubine Wei Linlang, she unexpectedly won the favor of Kangxi Emperor Xuan Ye. She thought it was the beginning of a good relationship, but she didn't know that the "likeness" was both honey and arsenic - Xuan Ye's tenderness concealed his guilt for the deceased, and the queen's "sisterhood" was wrapped up in the plot to kill her.
The sword flash at the birthday banquet, the poison in the dinner, and the rumors of the "Demon Queen" followed her everywhere, drawing her into the whirlpool of strife in the harem. She has transformed from a fearful girl into a wise man who can dance on the tip of a knife. She hides her edge by giving in to show her strength.
But when Xuan Ye called out "Linlang" in his dream, when the queen's hypocrisy was torn apart, and when the mark of the "substitute" became deeper and deeper, she understood: the love within the palace walls has always been mixed with calculations and obsessions. He is trapped in the past, she is trapped in the present, and the net set by the Queen is tightening little by little.
The orange flowers bloomed and withered, and she held her sincerity like broken jade, turning it over in the palm of the emperor. Should he become Wei Linlang's shadow, or should he break the shackles and be himself? This love, which started out similar, will finally come to an end in the wind and snow of the Forbidden City.
