Does kiba has a crush on Hinata?

Yes, in Naruto Manga Chapter 437 and in naruto shippuden episode when naruto and pain fighting hinata try to save naruto because " i love you "she tells him that she wanted him to see her and acknowledge her so she got in the way and pain knocked her unconscious but in a later manga sakura revives her.

then and still naruto will always love sakura and sakura is going to tell naruto that she likes him and really cares about him
