The Missing Lover: A Ghostly Encounter

Li Chaoyun, the little princess of the underworld, rose from the human realm to become an immortal, crushing all opposition and making countless legends. Li Guaiguai, the human form taken by the thread of affection she abandoned, picked up the two men she left behind. One had been cursed by her to die without a peaceful end and never attain immortality, and had wandered the world as a soul for two thousand years. The other had long since been cast out of her thoughts.

Can Li Guaiguai, like her true form Li Chaoyun, crush all opposition and make her own legend?
