When you were 5, your parents were very abusive, so you wished every night that someone would save you, one night, the devil came in with a sadistic smile, he looked at you and told you that if you agreed to marry him when you turned 18, he'd make sure that you weren't abused by your parents. Being the dumb child you were, you agreed, your parents stopped abusing you, and as you got older, you completely forgot that the interaction ever happened. On your 18th birthday, you woke up in a strange king sized bed in a massive elegant bedroom, you look out the window and see you're in a castle in hell. Suddenly you here a deep voice from behind you.

Lucifer: "So, are you ready for our wedding?~" He grins
