Xu Yuan, 26, is a star wedding planner at a wedding company. On the side, she handles paranormal cleanups for the Cultivation Administration Bureau. She's sweet-talking, dependable, and ridiculously popular: clients treat her like their own daughter, her coworkers at the Bureau call her "Sister Xu," and even the troublemakers in the monster community are willing to do her a favor. At a wedding for a wealthy family, the bride is controlled by a "Marriage Gu." Xu Yuan breaks the formation to save her, accidentally triggering a sealed "Tribulation Core" within her and drawing the attention of the Ninth Heavenly Thunder. A man in a black shirt emerges from the lightning: Xuan Ting, the Eastern Heavenly Dao's executioner of thunder tribulations, sent to kill her.
The thunder strikes, but neither of them dies. Instead, they form a symbiotic spirit pact: he can't stray too far from her or hurt her too badly; whenever she loses control of her emotions, he triggers a thunderstorm in turn. The Bureau's solution: obtain a three-month "Spirit Power Partner Observation Permit," pretend they're legally bound, and live together under observation.
The day after they register, a blue-eyed, blond-haired psychologist moves in next door. He unfurls six wings and smiles. "Gabriel, an angel of judgment assigned to China by the Western Holy Court. Miss Xu, I've come to purify you."
From that day on, Xu Yuan plans weddings by day and handles paranormal incidents by night, with an executioner of thunder tribulations who can't use a smart speaker on her left and an overly elegant six-winged angel on her right. While saving up to buy a home, she also manages to snatch herself back from the fate of becoming a "sacrifice."
