When gifted fortune teller Park Do-A dies, she transmigrates into the body of Bunnie, a curse absorber for the daughter of an archduke. As the new Bunnie, she befriends Demian, a boy prophesied to bring ruin to the empire. But when Bunnie reads Demian's fortune, she learns that, actually, he has the potential for greatness and prosperity, so she decides to shape him into the next emperor instead. Will these two be able to defy destiny and rewrite their futures? Or will the curse of fate prevail? (Source: Tapas, edited)
