Nightmare x Killer

There might be some angst or nsfw, and updates will be slow. However I guess there is some things that you'd need to know about this AU. I also post some of my arts at some moments.
Nightmare:
-In his uncorrupted form.
-USED to be the villain (basically aftermath)
-Kinda serious and sour at the times; after all he had eaten the apples in this AU too.
-Awkward with his brother (will be working on that)
-Still likes books
-May get tentacles/corrupt if feelings are unstable.
Killer:
-Still asshole
-Makes puns 24/7
-Currently feels emotions, but faintly.
-Soul form is stable for now.
-Might get crazy at a times.

These two live in the same house, with different rooms of course. They live pretty much normal lives, as they won't be let to move to travel in different AUs.
THESE CHARACTERS STILL SUFFER FROM THE AFTERMATH OF THEIR ACTIONS IN THIS BOOK. Remember this revolves around Nightkiller and their relationship.
Side ships:
-Cross x Dream
-Error x Ink
maybe others too
