Sorry but i disagree here it's not like that it works.
I was neutral but a neutral does not read the things only to pick the big picture you just dont concentrate on pairings, you try to look for other stuff.
I said that you dont hope for every chapter to come an NS moment but you do hope that on the end of the arc on on the very ending for a NS and got concerned when a NH stuff happens like 615 with almost 100% of the fanbase here scream NH canon.
You simply does not care, pairing fanservices does not affect you.
It obviously works that way for some people since I am that way. I have never said NH was canon (although other people were) and I actually didn't really have a problem with that particular moment happening (obviously it was going to, Kishi always super hints at certain events). I just had a problem with it happening during such a crucial moment for Naruto when until that moment, it was Sakura who filled this role the most out of the K11. (It could have happened any other time, but I think that moment was 'too high' and Kishi will have a hard time making NS moments afterwards shine brighter. He can do it, but still)
There is not one definition for neutral. There are people like you describe that simply do not care and will read for the action or -insert other stuff-. Then there are other neutral people that, while they have a preference for a certain pairing, fanservice still doesn't affect them as much as it would most pairing fans. While I prefer NS, I also wouldn't mind if there were absolutely no pairings at all by the end of this series. NS stuff is nice, but overall, I can't say that NS is the reason why I like this manga or the reason why I read it.
Even if NH or SS happened in the end, while I think the story would be completely and utterly ruined, I just don't think I'd stay mad for very long. I can look at NH and SS moments completely separate from my preference for NS. This ties into the fact that if Kishi had built up any other pairing as he has NS, I would probably ship them. I think it also helps my situation that I did not like NH or SS WAY before I liked NS or even knew that the fandoms existed. I guess when I say neutral in this situation, I mean objective.
Either way, the more Kishi tries to tie romance into the story (which he has done a lot of lately) the less amount of neutral fans will exist because the he's making the romance an important part of the story. (which I'm not sure I like)
