I don't know... I'm kind of fond of th idea of having someone of an opposite personality. Matsumoto's warm enough, but,
er, not the right type for Hitsugaya, romantically. As partners/ captain and lieutenant, they makes one heckuva team,
though. :D
Hinamori idolizes Aizen to the point of unhealthiness, which causes Hitsugaya more pain than anything, so she definitely
wouldn't be right for him.
On the whole, I must say that as of right now, I don't think there's a girl for our beloved little captain yet.
As far as Orihime goes, I do feel for the gal. She's rather getting the raw end of the deal. Ahhh, good ol 'love triangles.
