NaruHina! My explanation is that Hinata always understood Naruto and always admired him. Even when they were kids, when everyone looked down on Naruto, Hinata always liked him. To me, that's real true love!
To be honest, I'd be real upset if Sakura ended up with Naruto

It just would not be fair for Hinata at all. Also, Sakura was always in love with Sasuke so turning to Naruto "just because" would be a bit annoying, even though her character changed.

If anyone got so extremely far ahead of the chapter as to read "Hinata's confession", WHY DID NARUTO FORGET HER CONFESSION AFTER THE BATTLE WITH PAIN (or Pein w.e)!?
Just does not make sense...
