It has been a while, I haven't been following Hetalia fandom for about 4 years now...
So, all I can recall is that this is a fanfic that starres the whole world I think, there is a war going on I'm not sure who started it though...It was on LJ and it has really short chapters but they are exciting...umm..jeez I cannot really remember the plot at all I just know that it's a wonderfully written piece and since I left the fandom years ago it might be completed!!!
Ok there is something, Scotland and France have feelings for each other. It starres Wales as well somehow...I know this is not much at all, close to nothing, still somehow I hope someone recognizes it. :)
