Kill the Villainess

Eris Mizerian was the villainess of a novel. The only daughter of a marquis, she got executed after scheming against the pure and lovely protagonist, Helena. My only goal, after possessing her, is to leave this world and go home. I'm prepared to face even death... but the laws of this world keep stopping me. A changed Eris begins to draw the attention of three men who once loathed her; the Crown Prince, the High Priest, and the Knight—"It doesn't matter. I'll never be able to love this world." Even if the only way out is death, even if the only way out is to make a deal with a witch... I'll leave for sure!
