The story centers around Wang Ying and his love triangle with Tang princess, Li Jing and fox spirit, Xiao Wei. When Princess Jing’s face becomes disfigured, she willingly exchanges her human heart with Xiao Wei, foolishly believing that Wang Ying will love her again after she regains her beauty. Though it is a supernatural epic, the main theme will be love and the sacrifices involved. (Source: Viki)
