Yup! There’s a few hints here and there that I’ve got marked down in my notes. It’s not just FrUK either. Both France and England are hinted at sharing romantic feelings for other nations. They’re very subtle though, so I wouldn’t jump the gun on them. 

Anyways, the most obvious hint of FrUk for me is when France proposes to England by asking him to merge their countries; this being a result of the Suez Canal Crisis. 

I know the picture’s resolution isn’t great (it’s the best I could do), but in the far left of the second panel, England says: 

“I don’t want to get married for this lame reason.” 

I don’t know about you, but if I was vehemently opposed to marrying someone, I wouldn’t need a reason to reject them other than simply not liking them. It doesn’t seem like England is completely against the idea of marrying France. I don’t find this too hard to believe, as we’ve already seen male countries marry each other before. 

It’s definitely possible, I’m not ruling it out. I’m just not so sure if we’ll ever be blessed with an obvious enough confirmation.
