I woke up as Grace, a lustful and greedy villainess in a novel. Grace is a mere stepping stone, someone who toys with the male protagonist, Zane, and gets dumped to facilitate his meeting and falling in love with the heroine. If the two fall in love and the heroine's saintly abilities awaken, a war with a neighboring country will be averted, and Grace will live. Wanting to avoid that fate, Grace decides to fulfill her role as a plot device. However, being poor and inexperienced with men, Grace's attempts to act like a lustful and greedy villainess backfire, increasing her favorability with those around her. Moreover, Zane, who somehow became her lover, is not cold but rather overly sweet, making Grace flustered. "Even if you run away, I'll chase you to the ends of the earth, so you should give up." "I'll absolutely never let you go." Even when Grace tries to break up with him, he chases after her, and even when she meets the heroine, he ignores her. Furthermore, the reincarnated heroine is far more villainous! This is a romantic comedy about Grace, who can't quite become a greedy villainess, and the cold (to everyone but Grace) high-spec Duke's chase.
