Cursed POV: I'm Just an Extra, But I'll Kill the Villainess

[Ding!][Congratulations!][For your heroic sacrifice, you have been chosen to reincarnate into one book of your liking.]I died once, working a seventy-two-hour shift as a surgeon. My heart stopped from exhaustion. But I managed to save countless lives during a pandemic maybe that's why, when I was supposed to ascend to heaven, fate had a different story for me.[Make your choice...]At that magical moment, I couldn't think of anything at all so I chose the last book I had read: "Beyond the Horizon: The Legend of the Moon Heroine."But instead of reincarnating as a follower of the heroine, I was transmigrated as the villainess's puppet. A young woman named Beatrice Vermelion, a cursed vampire who dies at the heroine's hand in the very first chapter. Someone even I had forgotten until the end of the book, when it was revealed she was the last successor of the royal bloodline. Her family had been slaughtered by the villainess, and she was forced to serve her, never knowing the truth.I should have died as well. As her. Or maybe as me? It's confusing, living in another body with the memories of my own world. But I know this much: in this world, I will forge my own fate. Even if I'm just an extra, I will kill the villainess before the heroine can. I will take revenge for this girl, even if it makes me the enemy of an entire world.I will not lose. I will not be forgotten. I will use my surgeon's skills to seize this world,as the new villainess.Join my Discord Server! Link below:https://discord.gg/YxK5KqWrUa
