How about the Nordics with a petite plus size s/o, please?
Norway: “I think you’re still cute..”Lukas wouldn’t care if his s/o was plus sized or not. He’d see his s/o as beautiful/handsome no matter what size they were, and he’d remind them that if he ever saw them looking down. Lukas doesn’t often express his emotions, but if his s/o ever needed a pick-me-up, he’d tell them that he loves them just the way they are.
Iceland: “Who cares what anyone says..!”Emil would always get a little bit peeved whenever someone were to say something bad to his s/o, or make his s/o question their body. He’d love them the way they are, and would always tell them that he thinks they’re adorable. What’s wrong with being a little chubby? It’s just more to love.
Finland: “Never change!”Tino would love his s/o regardless, but would find them adorable if they were plus sized! They would be super cuddly to him, and he’d think they would look good in anything! Tino would also often tell his s/o that them being plus sized means they’re a great pillow, and big thighs mean more room to hold puppies!
Sweden: “…What’s wrong with that?”Berwald wouldn’t see why being plus sized was a bad thing, so he wouldn’t care whether his s/o was or not..as long as they were still healthy and happy, he’d be happy with them. He’d also occasionally kiss over their skin, just so they know how much he does care about them.
Denmark: “Think of it this way, you will survive the winter!”Matthias wouldn’t care at all! He would see it as they are the perfect size to cuddle with him and with both of them under the blankets, it would be so warm and cozy! He would always tease them about being arm rest height or a coat rack for him, but it would all be in good fun! As long as they still enjoyed going out with him to theme parks or out for walks, he wouldn’t care!
