One night, you had found it difficult to sleep, and the only demon awake was Satan. Supprisingly, he agreed to help you sleep under the condition that he can read to you. Which, of course, you agreed. Part way through the book, your eyes became droopy, and you ended up falling asleep. Not registering the fact your head was on his shoulder, he looked at you with a soft sigh and a smile. Satan put his book down and grabbed a blanket, draping it over both of you and drifting to sleep with you.
