SasuHina has always been a pairing that intrigues me. I know in canon Sasuke and Hinata hadn't even spoken to each other, but just the idea of them being together is fascinating. Neither are too loud and are controlled. They both come from Clans with regulations and laws. They had father issues. And Hinata never really worshipped him blindly like how all the other girls did when he was younger and I can see Sasuke find that a little appealing. I always thought all the fangirls annoyed him.
Of course, Sasuke's very rude and blunt so Hinata's self-confidence might not be the best match for him if he can even bring Sakura down. But I feel like Hinata could understand Sasuke and not be so pushy and forceful with him like everyone else. She's really sympathetic too so that also helps. This pairing just feels really harmonious and peaceful. Not a lot of pairings, whether canon or not, have that.
I don't really ship Sasuke with anyone because it's OCC, but I like SasuHina for fanarts and crack fanfiction. I'd like to write a SasuHina fanfic at some point to develop them properly from canon, but it would definitely take a lot of work. You'd need to give them a lot of interaction and meaningful moments, particularly on Sasuke's end, to do it right. Hinata's also really obsessed with Naruto too do you'd need to work with that. But I'm okay with a challenge.
I agree with everything. If they ever became a pairing, their development would be really interesting. I'd expect it to not start out very well, but then they would start to gradually accept each other, and then possibly be attracted to each other. That's how I see it. And man their characters are really complimentary >.< I love it~
