Grace is supposed to toy with the protagonist Zain, dump him cruelly, and serve as a stepping stone for the heroine to fall in love. If the heroine's holy powers don't awaken, a war will break out with the neighboring country, and Grace will die. Determined to avoid this fate, Grace decides to play her role as a stage prop. However, being a poor actress and inexperienced with men, Grace ends up raising the goodwill of those around her instead of being the villainess she's supposed to be. To make matters worse, Zain, who is supposed to be cold, turns out to be overly sweet, leaving Grace confused. Despite her attempts to break up with him, Zain chases after her, even ignoring the heroine when she appears. And to top it all off, the reincarnated heroine turns out to be even more of a villainess! This is a romantic comedy about Grace, who can't fully embody the greedy villainess, and the high-spec duke who is cold to everyone except Grace. * The title has been changed from “The Ex-Girlfriend of the Cold Duke, Who Was Supposed to Be a Villainess, Won't Let Me Go Even When the Heroine Appears!” * Also available on Kakuyomu.
