You have the ability to bring unlucky, and when you were going to give up on living a life full of unlucky, a man challenged you and ends up being hit by a train, but somehow he heals from his injuries and decides to stay with you. A few days pass and he continues to try to understand this unlukcy so that he can finally die, as he is immortal and has been living on Earth for decades.
