I Reincarnated as the Villainess and I Refuse to Follow the Plot

I died... ...and woke up as Kyla Thornevale - the villainess doomed to die in How to Snag a Prince. I knew every betrayal, every death flag, every tragic ending and none of it stopped fate from dragging me back when I tried to escape. Now I must survive high society, the heroine's schemes, my murderous fiancé, the unstable Crown Prince, and the knight and mage who wearily watch me. And with new players entering the field - ones who never had a role in the original novel. The plot is shifting, for better or worse. The story wants me dead. I refuse to accept my fate. My goal is simple: Survive at all costs. — Description from novelcodex.org
