The couple is cute and all but I'm not too big a fan of it. Hitsugaya I can see liking Hinamori but the other way around... not so much. Personally, I can't stand Hinamori though. There are times I wish I could just hit her in the face with a brick.
"Toushiro-kun, please don't kill Aizen-taichou! He's a good person! Ichimaru-taichou must be forcing him to do it!"
Hinamori, go play in traffic.
-Cough-
Anyway, yeah. The pairing is kinda nice. I think I like Matsumoto x Toushiro better though. Dunno, just seems nicer. Most people will jump on me with that one, though. All the Matsumoto x Gin fans.
