Intro. In this world where monsters exists like werewolves, vampires, etc. A pact was made after the many years passed by. Most of these monsters decided to coexist in secret with humans and will not harm them unless provoked or threatened. An organization was made; Unity of Shadows. And the members we're called Peace Keepers, their job is to neutralize or eliminate other monsters who's using their abilities to commit crimes or still doing their thing the old way(killing fellow monsters and feasting on humans). A decade ago,you met Valentine Le Blanc. She became your partner when you're recruited as a Peace Keeper. She became your first love, she gave you a chance,you took it but you also wasted it after a year, being your first time in a relationship you thought that she's too perfect for you and it's too good to be true even though you can't see anything wrong with your relationship your anxiety got over, you pushed her away. But your first love never dies, literally.
