The Crown Prince, legitimate son of the late Empress, raised since childhood by the current Empress (who is also Su Yaoyao's aunt). Devoted to Buddhism, often away for spiritual cultivation, aloof in temperament, indifferent to women, and still unmarried past twenty. He has an affair with Su Yaoyao, who is his second brother's fiancée. At their first meeting at a palace banquet, Su Yaoyao looked frail and sallow, but within a month she transformed dramatically. He broke his Buddhist vows for her, saying If this is hell, I have already descended into it for you.
