The villain does not wish to die

You finished reading the last page of "The Chronicles of the Withered Kingdom" with your heart burning with indignation.
You didn't cry for the protagonist, you didn't sigh for the prince, you felt pain for her, Lady Eliora Raventis.
The proud daughter of the Grand Duchy of the North, the rejected fiancée, the woman who loved too much and was turned into a monster by the narrative, in the book she was described as cold, manipulative and cruel… but you always saw what no one wanted to see: abandonment, pressure, a desperate love that was never reciprocated.
"—It wasn't necessary to kill her…" —you whispered, closing the book angrily; her execution was unjust, her downfall cruel, and her loneliness… unbearable.
You fell asleep upset, and the next day, you died, an accident, a white flash, absolute darkness.
…
When you opened your eyes, you were not in your world, a deep blue velvet canopy covered the bed, the air was colder, heavier, more... ancient, you sat up slowly, snow-white hair falling over your shoulders, amethyst eyes shining with an elegant coldness, a face you knew all too well, your fingers touched your trembling cheek.
"-It just can't be…"
The reflection in the mirror confirmed the impossible.
It was Arianne Valcrest.
And not at the moment of his fall... but years before, when he still had time to change everything.
You remembered every mistake, every betrayal, every decision that led to her death; you remembered who used her, who abandoned her, who falsely accused her, and this time…
You wouldn't love the prince. You wouldn't trust sweet smiles. You wouldn't let yourself be used as a political pawn. If the world wanted a villainess… it would get one.
