非NP It's a tag from a novel but I don't really know if this is supposed to mean No Pair or is NOT a no pair hehe
np/no pairing doesnt necessarily mean harem though, harem means more than 1 person v1, np is no one in particular and yeah i think its *not np* so there is a pairing
it means no CP. what's really funny to me is that np is there is a meaning of n=#of people p=pairings NP can also mean a harem. 3P=threesome and so on... but in this context it means no CP or no harem.
