I have to agree. It's annoying when even the same artist draw similar looking MCs for different manhwa.
I agree but they are just using common features that are seen in Korean people but they can change hair color at least for the minimum and at most more changes to their mc
Tbh I think it's less authors modeling their MC's after Jinwoo and more authors making their MC's look like the beauty standard for guys in Korea; short black hair that's almost always parted midway, strong angular features, bodies that aren't too skinny or muscular, etc
Just look up "Korean male beauty standard" and you'll find most action MC's look like the guys in the example pics lol
Before I continue this after chapter one, I just wanna say.. Can please kprean authors stop reusing solo leveling mc's feature again and again and again, it's irritating now, half of these action manhwa mcs look like the copies of jinwoo nothing else. At least change the eye color man, facial features too. Ugh
