I am a nerd and read the chapter again. The "girlfriend" scene reminds me of a similar moment -- when Tazuna and Inari showed up to help rebuild Konoha.
Remember this from #451?

The love triangle
did exist then, at least as far as Naruto was concerned it did, but he lied about it. You can tell he's lying not only by his words but by his expression and posture as well. And in manga time, this scene didn't happen all that long ago.
But now we have #631....

We get a significantly different expression and response from Naruto. And he could just as easily have lied here too if he was too embarrassed or uncomfortable, or if he was worried about embarrassing Sakura like he was in #451. It's not as if Minato would have known the difference any more than Tazuna and Inari did.
But outside of a momentary fumble -- which was presumably caused by his dead father asking such a blunt and unexpected personal question -- Naruto tells the truth.
So what was it, specifically, that emboldened him to answer yes this time?
Two significant things occurred between the two scenes: (1) Sakura's confession, and (2) the other Team 7 "reunion." Somehow, in the mix of all that, it would seem that Naruto came away with a confidence in his chances with Sakura that he didn't have before.
Was he more convinced of Sakura's love than he seemed at the time? Did what Sai said later convince him? Was it a combination? Was it because Naruto saved Sakura from Sasuke's murder attempt, and that changed his mind about standing on the sidelines?
It's not shocking or anything, because despite the problems with her confession Naruto did get some serious encouragement out of it, but I didn't see it then the way I'm seeing it now. His answer in #631 was a qualified yes, so he's acknowledging there are complications and he's not being
stupidly confident, but he asserted himself and his feelings in a way he never has before.
That's kind of a big deal, I think, and it really makes me wonder how it's going to get resolved. Not that I wasn't wondering before....
ETA: I forgot to say that it's interesting that in both cases Naruto answers before Sakura can. o__O
