Kiba and Hinata have been chosen as Special Lovers 8, maybe Naruto will be disappointed with this result but it can be refrained that Hinata would be better with Kiba. If we read Naruto manga or watch the anime lately, Kiba become more closer with Hinata not just in training, they also appear together more often than before. Meanwhile Naruto and Sakura look like become more comprehending each other. I think it wasn't complicated anymore, I agree if Kiba with Hinata while Naruto with Sakura.
You see that, Kiba is perfect for Hinata, I'm sure that Hinata just feeling pity and admire Naruto for what he did for her, but her truely love is Kiba. And how about Sasuke, who is the best girl for Sasuke's soulmate if Sakura would be Naruto's soulmate? You will get the answer on my next posting
