You're reading the wrong manhwas then. Brothers without a tomorrow make a lot of darker skinned characters for example. I could list all the manhwas I'm reading/have read that have a dark skinned character too.
Tight fit
Seven sundays (tan, but still darker skin)
Past friendship (tan, but still darker skin)
Slammer dogs (tan, but still darker skin)
Eye of the storm
Write me, touch me, read me
The secret life of the demon king (tan, but still darker skin)
The duke's debt (tan, but still darker skin)
Entangled!
My purrfect boss!
Dawn of the dragon (tan, but still darker skin)
Plaything: the grand duke's boytoy (tan, but still darker skin)
Tied up
Between fate and fortune
Leash me up
Dear door
Cigarette burns
Love gym (tan, but still darker skin)
Brotherly xx (tan, but still darker skin)
Rabbits ejaculate in 3 seconds
I could go on but I think that's plenty to prove my point
Iโm never gna see a speck of melanin in any manga/manhwa am I?
