Welcome to Hell Mephistopheles x Reader

One day you wake up to have an abnormal morning..
You kept seeing this 6'4 tall man with the strangest orange facial hair. It was as of he was following you, but you didn't let it bother you. Your life sucked, your mom hates you and she murdered your father. Your neighbor's son murdered their own parents, and you were fixing to be let off your job. How could it get worse? The man it followed you everywhere! You about had enough, but you still didn't let him bother you. Until you said, "What do you want?"
