Jinjoo finds herself transported into the world of a fantasy romance novel, but not as a protagonist—she is now the Demon Queen, Astreia, the story’s villain. If she doesn't alter the plot, she will be killed by the warrior Caine. To avoid this fate, Astreia attempts to end the conflict between humans and demons. She must gain the trust of both sides, as well as that of Caine, who remains wary of her. Whether she can change her fate or is doomed to follow the novel’s original course remains uncertain.
