The Original Female Lead Ran Away

I reincarnated in a R-19 reverse harem novel as a villain who attempts to kill the female protagonist but fails and dies. I want to break off my engagement with the fiancé who’s supposed to kill me and live well, but the female lead, who successfully seduced one of the male leads, has returned to her original world. Leaving me with the remaining male lead candidates! “I hope you, as the new female lead, will overcome the adversities well. Fighting!” “Wait, just a moment. Wait! What am I supposed to do if you leave like this!”
