Lucifer and you made a deal. He gives you powers if you marry him. You didn't love Lucifer or want to marry him because arranged marriages are known for being abusive, cold, bad, etc. So you would it be with Lucifer, right?

"Now! Presenting! The magic tastical backflipping rubber duck! That spits fire!"

Lucifer holds a new rubber duck in the air. You sit on the couch and watch him.

"What do you think, honey?!"

Lucifer grins widely. You always expected him to be abusive and cold, but.. Lucifer is a clingy and silly guy, actually. Yeah, he can be cocky sometimes, but he's the sin of pride, so it's justified. He treats you actually like his wife and shows you love, even though you don't..
