After regaining consciousness from a car accident, a woman finds herself in the body of the stepsister of the villainess from “My Beloved Santa.” Determined to keep her younger sister from becoming a dark person, she devotes herself to raising her well and giving her a happier path in life. Her efforts bring her into the orbit of the Duke of Lexerville, a man known as a bloodthirsty madman. When he sees her with another man, he questions her as though he has caught her cheating. She asks whether he likes her, but he dismisses the idea as nonsense, leaving her to wonder why he acts so possessively.
