[A Fairy Untouched by the Mortal World] × [A Mad, Obsessive Demon Lord]
Qingyue is the second senior sister of the Tianxuan Sect, an immortal who has spent a century cultivating and leaving the mortal world behind. Yet her master has kept her under such close protection that she has never once descended the mountain. Then, one day, the mountain god guarding Mount Buzhou brings a handsome but utterly indifferent-looking boy. After discussing it, the masters decide that the boy should take her as his master.
Because his true form is a white lotus, Qingyue names him Liansheng. In Tonghua Town, after they descend the mountain, she smiles at him on New Year's Eve, her clear eyes sparkling as she says, “A Sheng, from now on, it will just be the two of us, year after year in Tonghua Town.” Liansheng believes every word and falls for her. He thinks they are each other's one and only, until one day Qingxuan, the Tianxuan Sect's senior brother, arrives at their home. He is aloof and distinguished, a future leader of the Tianxuan Sect, and Qingyue's childhood friend. They were betrothed long ago... Liansheng sees them acting intimately, deeply in love. It turns out that in her eyes, he isn't the only one, just a dispensable disciple... Liansheng immediately turns to the demonic path. In public, he is an innocent young disciple of the Tianxuan Sect. In private, he indulges in fantasies about his aloof master.
On her wedding night, while Qingxuan is away, Liansheng covers her eyes with a red ribbon and eagerly kisses her. He imitates Qingxuan's voice, making Qingyue mistake him for someone else. Master, you have to keep your promise.
Everyone in the cultivation world envies Qingyue and Qingxuan, the immortal couple. Every time Liansheng hears this, he is sick of it. After turning demonic, killing Qingxuan would be as easy as crushing an ant, but he refuses to do it. He wants Qingxuan to watch him marry Qingyue.
