RusAme is my OTP for Hetalia, but I don't mind AmeCan or RusCan, either. x3;
PruIta (probably my OTP), GerIta, Spamano, SuFin, Holy Roman Empire/Chibitalia, and little bit of FrUk I suppose. But I basically ship Prussia with everyone (including himself XD).
Hoo boy, I only just recently started shipping, but I'm fairly fond of RoChu.
Heh, it's been a while. I guess my pairings are mostly the same... Gerita, Spamano, USUK, PruCan, Frying Pangle (because I can't decide...), Rochu, GiriPan, PolLiet, SuFin, DenNor, and when I feel crazy I might ship KimchiBurger...
RoChu and RusAme. That is all.
Well... My Hetalia OTP has changed to something that there is so little fanart of, it's sad. I now ship RusEng. The canon conflicts Russia and England have are so adorable. :3
