Evelyn Harrington, a supreme member of a luxury brand, receives a rare succubus named James Moore as a gift. Instead of obeying her, James loathes Evelyn and only obsesses over her scheming half-sister Vivian Harrington, even rejecting her care to risk his life for Vivian. Heartbroken, Evelyn applies to exchange the "defective" succubus, and the brand sends a top-tier replacement—Ethan Collins. Ethan is loyal, passionate, and utterly devoted to Evelyn. Meanwhile, Evelyn exposes Vivian’s lies and manipulations, shattering James’s illusion of true love. James is taken away for destruction, while Vivian and her mother Jennifer are disgraced and exiled. Finally, Evelyn lives happily with Ethan, free from her painful past.
