That you don't want to read the story because the subject matter is sensitive, or whatever the reason, is perfectly fine, but to complain that biracial or Native American representation is wrong, when it's a manhwa where the characters are mostly Korean with light eyes, blonde or colored hair, and no Asian features, seems like you were asking for too much But if you don't want to read it or don't like it, that's totally valid.
But what I'm saying is that in all the other manhwas, the characters are Korean, and none of them look Korean! There are characters with light eyes, blonde hair, red eyes, and in the story, their nationality is Korean. I'm not saying there can't be Koreans with light eyes or hair that isn't black, but I don't understand why it shocks people so much that a person of Native American or biracial descent appears in a manhwa with light eyes when most artists don't respect true features when they don't even do so with their own nationality.
That's absolutely right! I'm Latina, and when the author of *The Dirtiest High* said in her creator's note that she did extensive research to give the MC a proper Latin name, it made me so happy! You're right, it was the least she could do. But well, at the same time, they're manhwas, so I don't know if I can expect too much, even though we'd like to.

Bye the ml isn't even a good representation of a biracial or native American. His character design favours white features. It's not impossible but rarely do you see an indigenous have blue eyes.
