Why is this "korean badboy aesthetics " Only associated with korean?

[Fynasids dk]

How does it different from the classic?
And how much the appeal differ

 

[TheBrownOne]

Basically, just any Yellow Asian whos tall, has black hair, wears dark shirts, long black pants, has tattoos, big forearms, wideish scapula, works out, and has a medium-length hairstyle

(98% of yellow asians get canceled out at the tall and wide scapula part)

It stems from K-dramas where the main guy is always some rich young (maybe bad boyish) CEO who falls for some loser nerd girl who doesn't like him (JFL scenario)

I'm assuming a "Korean badboy" is a Korean who gets a B- on a math test or something
