sooo idk sometimes i think about what if Nightmare actually dated someone? Not being for, like, using it for achieve his goals somehow but just because "hhhmmm yes you look dateful enough for me" (and this is funny for some reason)
(also, i guess that's not going to be a very healthy relationship in any circumstances but-)
Ngl I can’t really imagine Nightmare to be the romantic type at all (cough I headcanon him to be a repulsed Aromantic cough)
I can still see him be in a relationship tho, and Nightmare’s way of choosing a partner is literally just based on how much negativity he can squeeze outta them hdhdhshhs
And ain’t that just Fluffynight in a nutshell
