Let's see one thing here:
After he defeated Pain, what does Naruto do first?

He is wondering where Sasuke is.
Now let us see what has happened beforehand:
Naruto learned that Uchiha Madara, the founder of the Uchiha clan, who should have been dead for decades, is still alive and that he was behind Akatsuki, Kyuubi attack and thus, Kyuubi sealing inside him.
He also found out that his father was the Fourth Hokage. Isn't that a shocker for him? Apparently not.
The most important thing is to chase after Sasuke right away to beg Raikage to forgive Sasuke.
And that's only a dent of it. The next panel is a proof that Naruto is at least a bisexual if not homosexual. Normal guys do not think about their best friend in that way when they go to sleep.
