Yep! No fanmade stuff here, folks, I'm going to try to list all the relationships in Hetalia! This includes who hates who, who's related to who and how, who has a crush on who, everything that involves two characters interacting! Please remember that I'm ONLY putting in stuff that is true for the original work. I don't care if you think Poland has a crush on Cuba or if you think Canada loves France. If it's not true in the original work, it's not being put here. Please remember that there's a high chance that I'll miss a bunch, so please put a message in the comments if I forgot one or if I got one wrong. Thank you, and here goes nothing!
