I died today

So today I died because of heart attack. When I woke up I found myself in a luxurious bedroom. I looked around and saw a mirror. The girl in the mirror was familiar. Blond hair, pale skin, and red eyes. I touched myself and realized that this body belongs to Charlotte. I was reincarnated as the villainess in the famous book 'The Apple of his eyes' I read in my past life! I tried to kill the heroine may times and the worst part is that I will die in the hands of the Crowned Prince, Emir! So, I won't let it happen, I'll protect the heroine from the bitches who tried to hurt her and become her hero..

But everything became weird! The crowned Prince who hated me for a long time doesn't want to break off the engagement with me! and why does the Duke of Montefalco is asking me for a marriage?! And even the Holy Priest is being friendly with me? What in the world is even happening? Will I able to survive in this world?
