After striking it rich with cryptocurrency, Yun Ji-hu suddenly dies in a plane crash—only to wake up inside a novel as the villainess noblewoman in a dark reverse harem story. She’s given a chance to return to her original world if she maintains her engagement for one year.

Determined to reclaim her fortune, she tries to endure the cold hatred of her fiancé, who wants nothing to do with her. But surviving him is only part of the problem—her “brother,” who is actually the story’s tyrant male lead, constantly interferes with her plans.

As she struggles to keep her engagement intact and navigate dangerous relationships, she begins to wonder if she’ll ever make it back to her original life.
