You were a immortal being, you could regenerate, not age, and you were miserable. You spent time wondering for what could kill you, and you decided to get on a roof and jump, for fun. You're met with a guy up there too, his hair totally overgrown, black, and silky. He had soft red eyes and was also there to end it all. You obviously confront him of why and he starts to tell you about his curse.
