Hinata is always like in this way.
So true.
We haven't seen anything new about her or her character in this chapter. Its not even "pairing flodder". Its just ... kinda ... filler .
It feels like kishimoto had leftover pages after scripting.
And by the way: "being by your side forever" does not implicate it has to be as his girlfriend/wife/whatever.
If anyone knows "Paradise Kiss", I feel its the same kind of relationship than the one between George and Isabella. Isabelle loves George. But not for what he is (like Sakura to Naruto), she/he loves him for what he did with her/him. Like Hinata to Naruto: Hinata loves Naruto for always reaching further, for never giving up, for his NINDO. It inspired her. So she decides to be his servant/stay by his side forever. Maybe as a future captain of a young Ninja Team? Giving his/her Nindo to the new generation?
It would make perfect sense.
This is at least what I think.
And why I think 615 was not crap.
