Just watched the video. "OH, they went through so much to be together." Yeah, that's called bad development...
Wait he actually made a video about NH about the things they went through? OMG
Here is a brief summary of NH:
Introduction - Naruto thinks she's a dark shy weirdo.
- Hinata stalks the place where Naruto took the bells test (if I'm not mistaken) then Naruto goes there and sees her. They talk for about 20 seconds. That was chapter 88 I think.
Moving on to part 2 chapter 437, yes nothing happened in 349 chapters between those two. Hinata confesses and gets herself killed without even trying to help the one she claims to love. But hey who cares about Naruto right?
Then 614-615. Again nothing happens between those two in so many chapters. Naruto doesn't even bother with her confession.
They hold hands in order for Naruto to pass chakra. Naruto is focused on Neji and his friends, while Hinata thinks of Naruto's big and strong hand with Neji's cold corpse is laying next to her. Hinata is such a wonderful, amazing and caring person don't you think?
So yeah Naruto together with Hinata really went through a lot of things. So many things that you can't count them by using your fingers on one hand.
Hinata murdered her cousin 
Exactly Hinata is indirectly responsible for his death.
