The story follows a woman who gets reincarnated as Luibel, a background princess in a fantasy novel. Things seem to go surprisingly well when the novel’s hero, Hazen, suddenly proposes to her, and she starts to believe she’s changed the story for the better. But her happiness shatters when she catches him cheating—and realizes she’s not in the original novel, but in a terrible dating sim based on it. Worse, she’s just one of many girls Hazen tosses aside. Furious and heartbroken, she decides to get revenge. That’s when Anselot, a notorious “mad prince” from a neighboring kingdom, offers to help. Though they’ve never even spoken, he’s oddly drawn to her. What begins as a revenge plan turns into a dangerous, chaotic romance between a forgotten princess and a prince with a dark reputation.
