Headless Villainess

Headless Villainess summary:

Good afternoon, ladies and gentlemen.
In the current world I am a selfish villainess that lived as she liked, in the previous world I lived modestly.
The result of my self-centered, spoiled lifestyle was to be cheated on by my fiancee the prince who after conspiring with his lover, broke off his engagement with me and as the result of strict trial was that my execution was decided. And thankfully as a n.o.ble I got the ‘honorable’ death by guillotine.
And so after I got my head chopped off by the guillotine, I was reborn into the corpse…
Re”born”?
No wait, I don’t have a head, what are you telling me to do now?
