Dark Moon, Black Heart, two clans completely different in character yet same in types people, vampires. Dark Moon is the clan the holds the Royal Family, king Yunho and queen Jaejoong with their five children, Luhan, Yifan, Jongdae, Chanyeol and their youngest, the heir, Jongin. They are widely respected even out of the vampire world and everyone looks to them for guidance but the same couldn't be said for the Black Heart clan. Black Heart clan, evil and dark, the clan that hates everything and everyone except their own yet they are still very important, second in power after Dark Moon. No one would believe that Kim Junmyeon would be the leader with his husband Kim, once Zhang, Yixing with their appearance but they are anything but that. Their children, Jessica, Krystal, Seulgi, Joy, Baekhyun, Kyungsoo and Sehun all have a reputation, Kyungsoo's the worst. He is heir to Black heart and could not be better suited for it, his line of girls and boys he played, the hearts he has broken, the lives he has destroyed. So what happens when Jongin meets Kyungsoo? Their fates entwined as soon as they looked into each other's eyes. "Hello there, pretty boy." Kyungsoo drawls, smiling his sickeningly sweet heart shaped smile at Jongin who barely even glances at him, gaze fixed on the heavy wooden door locked in front of him. Oh, his dad is going to kill him. "Want to play?"
