In ancient times having a lighter complexion was a characteristic of the nobles since they did not have to work in the sun and therefore their skin was lighter
That is why this is endorsed in so many movies, books etc.
Considering the time setting used, it should be understandable
There's no such discrimination in the webtoon (considering the time/settings, it's normal. Most nobles do administrative works that's why it is normal for the commoners and nobles to assume that a person is a noble if they have a fair complexion.
But there's this thing called "common sense".
But i just wanted to point out how the commoners immediately think a person is a noble if they have a fair complexion (they thought Nuah was a noble because he has light hair&eyes) Not all nobles should be white... Being white shouldn't mean a person has better ancestry because that's like indicating the other people are inferior than whites... The noblemen could have a dark complexion and still be noble. I don't like this "white=upper class" stereotype. I wonder why having a lighter complexion is endorsed in so many books,webtoons,comics and movies...
It's bit saddening tbh and I'm feeling down about this even though I'm white myself. It just sucks... Like I wish I could change people's perspectives about this issue and make them understand that having a lighter color doesn't mean you're more elegant and classy. It doesn't mean shit!
