Please Be A Traitor

I am Nyla, the only daughter of the Duke. I was living peacefully.One day, I suddenly remembered my previous life. I was living inside a novel!My fiancé, Karpel, will become a traitor in the future and will die in the Deng River while the piece of land that I’m living on is set to be destroyed by a tribal invasion!I cannot lose the engagement which was hardly set, and I can’t let go of my lavish life.The engagement was forcefully set up even though Karpel said he hated me, but he’s only just 16 now, If I plan this well, won’t he grow up to be nice?“….I didn’t say that I dislike you.”“You look pretty today.”Boy, I thought you hated me
