Entering the palace as a substitute - Shen Zhiwei, a merchant girl, was chosen to enter the palace because she resembled Emperor Xiao Che, Bai Yueguang and Liu Yunshu, who died young. She clearly understands her identity as a substitute and puts on a perfect imitation mask for her family's survival.
Fake play to create love - Shen Zhiwei's "perfect performance" won Xiao Che's favor and confusion, but Xiao Che accidentally caught a glimpse of Shen Zhiwei's intelligence and stubbornness, and became curious. The two developed complicated emotions in their twisted relationship, but they also developed rifts due to the shadow of Bai Yueguang and the frame-up of palace fighting.
Bai Yueguang "returns" - a woman who looks like Liu Yunshu appears and claims to be "not dead". Xiao Che was ecstatic, and Shen Zhiwei was completely abandoned and turned into a laughing stock. She woke up, took off her disguise, and moved out of the palace.
The substitute awakens - "Xin Liu Yunshu" is actually a pawn in a conspiracy to frame Shen Zhiwei. Shen Zhiwei showed his resourcefulness by fighting back. At the critical moment, in order to protect Xiao Che, Shen Zhiwei risked serious injury with his own body. When she was dying, she tore up the substitute label and left a heartfelt declaration of "I am tired of acting" or "I am Shen Zhiwei".
Chi Wu - After Shen Zhiwei's death, the truth came to light. Xiao Che regretted it so much that he frantically tried to make amends but was unable to save his life. He spent the rest of his life alone, remembering Shen Zhiwei's true appearance with the dignity of an emperor, and died in regret. (Extreme BE)
Intent: In the deep palace where she plays the role of someone else's phantom, she uses her sobriety as a blade and uses her life to carve burn marks belonging to 'Shen Zhiwei', so that the emperor who chases the shadow can only embrace her burning ashes for the rest of his life.
