Formerly the Seventh Prince, now Emperor Chengxi. He has a chronic cold since childhood and suffers from it currently. He has a distinctive mole beneath his eye and is described as exceptionally beautiful with a sharp, cold demeanor. He harbors resentment toward Gu Jiao, refusing to reconcile with her over an incident from three years ago on her birthday. He is sharp-tongued, stubborn, and hides his true feelings. Despite claiming to dislike her, he seems to care deeply, as shown when he coughs blood after she leaves and immediately takes the medicine she brings back.
