I got 3 question for all of you :
Prior to 615 what were Naruto's feelings towards Hinata?
Did Naruto's feelings towards Hinata change in 615?
If Naruto's feelings towards Hinata changed in 615, how did they change?
Some of you may be asking me why I'm asking these question. My answer is simple, right now the NaruHina fandom is basically 51% 615 and 49% the rest of their shipping.
1. Most likely the same as they ever been, just plain friends. Considering nothing was done with hinata's confession, that is still ultimately on the ropes. Even after the events of pain, we see a flashback reason for Naruto's love to Sakura, he feels undeserving of her because he has still not fulfilled the promise, this also meant he was doing a noble thing with his unrequited love, he would only feel deserving of Sakura if he either finished that or Sakura came to him honestly on her own because she wanted, not what he wanted. He didn't accept it at the fake confession cause, he knew her better than that and knew there was a reason for her coming all the way out there, not just for a love confession, espcially with a full team. Naruto would not just deny Sakura outright, he would rather her be honest with herself and him, so if the point comes for when she really does love him and tries admitting it again, under different cirumstances he would accept it then because after the events of the reunion and possible shift to him and maturity, realizing who is important to her, etc. She would be open and honest this time, then Naruto would accept it (if things lead this way). Basically Naruto's love for Sakura is selfless and has an act of nobility, he does her a lot and though he hopes to be with her, he would only do it if both she and himself were fully accepting of it.
2. Still too early to call, I mean it was short and for what could have been a longer moment, he just lets go and gives it out to everyone else, possibly the plan was already in his head before the ten tails attack hit the ninja HQ during this time Shikaku transmitted his final plan to the allaince. The 2 short times Kakashi and Guy got their energy restored gave him a theroy that anyone could do it, considering Kurama also said transfering chakra was an easy effort for tailed beasts. Its easier to debate against his feelings changing rather trying to support that they have. With so little, its much easier to say it was only for friendship efforts and ending the story and development between Naruto and the huyguas until we see otherwise, hell until we see Sakura as well, nothing can say that his feelings for Hinata are somehow bigger than his love for Sakura. Its hard to argue that they changed even more because of the one panel for Sakura in 615 possibly being an indicator for future potential development off this event. This is all without the fact that Naruto has not shown any waivering feelings for Sakura, even then he would still forgive her for the event in most logical reasoning for his character, he is a forgiving guy, if he can come to forgive and respect Nagato, he can do it for Sakura espcially since Sai admitted it was partically his fault for driving Sakura to do what she did. Even then there has still been nothing in anycase showing he is over Sakura. Even though Naruto did remember Hinata defending him from pain, thats not enough, I mean there are many other things he remembers with Sakura doing something to help or encourage him now wasn't there? That memory could just be him seeing how there is more to her in talent but not outright just starting to love her.
3. If they changed, this is one tough issue for Kishi to fix, I mean Hinata is not even in 100 chapters, not really good to somehow make a character major when they are not even in 1/6th of the story, espcially compared to the others. If they have changed, Naruto would need just some rapid insane shifts in development to resonate with Hinata more and just somehow leave the past interaction with him and Sakura as only close friendship. Not to mention if NH is the way things will go, what happens to Sakura then? Where can he end her without going SS which would reduce the story to an insane fanfiction and leave Sakura and Sasuke adversely effected? This is something that would grow on from question 2, but its still just so hard. Its just the big problem here is Kishi had time in the past to develop Hinata more, make her into a more prominent character like Shikamaru or Tsunade. Hell even Bee is more important than Hinata. Only 1 real arc of importantce and 2 moments in the second half does not help the case of trying to cram a new love development this late in the series compared to one which actually has some mutality in it. Reason for NaruSaku is not because Naruto loves Sakura or Sakura showing a close friendship for Naruto, its how they both act selfless to each other and display mutual growth from their events and all the good and bad they go through caused on both of them, alone, and even to each other. The events ranging from the 4 tails to the fake confession, even when they were hurt in some way by each other, in many other ways aside from this, they still maintain that friendship and never saw each other any differently, I mean Naruto still calls Sakura, Sakura-chan its safe to say his appriation of her has not changed and Sakura still feels the same happiness with Naruto. Even as simple friends they enjoy each other and have the potential for a better relationship, one that gives the story a good goal and does no damage. Does NaruHina have anything as long and enduring? No it does not.
