The Duke’s Daughter Trained a Wild Beast

I transmigrated into a novel with the ending of ‘Everyone dies and the world is destroyed’. With that crazy development, this world is about to end soon… In order to survive, I proposed to the villain who will destroy this world. “Accept the marriage and take me.” By becoming the villain’s wife, I tried to stop the misfortune. Then after that, divorce would be enough. But… “You must have been terrified of the demon blood flowing through my body. It’s okay, I understand.” “Yes…?!” “Still, I can’t accept this. Even if you hate me, let’s go home and do it in my arms, please?” The thing that you’re tearing apart, is it our divorce paper?
