There was! I recommend " My Deskmate Can Vampire " and " The Demon Vampire Seizes Love ". The former was a beautiful fantasy novel, which described the life of the vampire twins after they went to college. They were sweet and harmonious with human girls. The latter was a romantic youth novel. It was about the female protagonist living in a world where she coexisted with demons and vampires. She was loved by the demon ruler and the vampire ruler at the same time, and a war of love began. I hope you like my recommendation.π
