The Second Prince of the Great Yong Dynasty, born of the favored Guifei. He comes from the Cui clan, one of the four great families. On the surface he seems gentle and refined as jade, but in truth he is deeply calculating and no less shrewd than the male lead. He is the male lead's greatest rival in the early years. He harbors ambitions for the throne through his mother. He warned his Fourth Brother not to harbor thoughts about Gu Sui'an, and a flash of ruthless malice was hidden beneath his gentle exterior.
