It didn't kill you!? ( Nightberry )

Please don't judge! I love almost every ship in undertale and the aus so if you hate it leave.

Nightmare and blueberry were enemies but nightmare didn't think that at all he thought blue was the best, one day he injected blue with negativity thinking it would kill him, get rid of the person who made him feel warm and fuzzy plus nightmare hated feeling warm and fuzzy, but in the end what will it really do?
