Lucifer

He's the devil who loves playing with everything, he's immortal. he never gets hurt. what if when the day comes when, his fate showed but he never knew anything about it. He just only knows about a girl he's bound to be with, so he can live longer. His curse is unbreakable unless they both fell in love with each other. He was given to live in years and years before the curse. But if the girl dies he'll die too.
