I have a question. I read the summary of the original novel and noticed that Ci Sha’s character doesn’t seem to exist in the novel. I noticed that the name of the male lead in the original story is Chen Xuan Qing. Does anyone know if Ci Sha’s character was created specifically for the drama?

Despite the fact I'm not understanding completely the story of this drama, I really love it. Cause I really miss Zhang Zhe Han e Ju Jing Yi as a couple. ??
