Where us your proof that tanned are being barbarians in countless other stories? The fact is, most barbarians in mangas are actually pale skinned/ whites being barbarians because most manga are from japan and mostly pale skinned live there. And they dont usually draw tanned skinned because the their fans/ the japanese dont like it. Just like in their videogames as well.
I'm pointing out how other stories with a tanned ML, they're often portrayed as southern barbarians who only knows how to have fun, who likes colors, who likes 'vulgarities'. Whereas, the white people of the north, the capital—are the 'knowledgeable' ones of the empire, classy, elegant, demure. What part you somehow missed out on that I typed tanned ML are sexualized by being stereotyped as barbarians—but the female lead would always be a white blonde woman? If that's not sexualizing to you, I don't know what is. I'm pointing out how these kind of colorist pairings are starting to come off as 'sexualized'.

Only read up to chapter 4 and girl... That fucking hurts. No prep, no foreplay—and the FL made a flood? Bitch, that's not how it goes. That feels like r@pe, really. Always with the "foreigner x southern tanned barbarian", so sexualized at this point. It's only starting and anybody could tell the next chapters will be unbearable smut to read.
