It's not limited to just this author or just Korean authors. This happens in all Japanese, Chinese and Korean works.
I have seen many authors mainly write seme as dark haired and when they write some work with seme with r@pe as backstory, they suddenly switch the seme to being light haired.
This is not even limited to BL, same thing happens with male characters in other genre.
Heck, even in hetro manga, women most often than not are portrayed with light haired.
For countries with predominantly black hair to first portray so many light haired characters, and further more portray these atrocities committed against them...

Not saying that doesn't happen. I am talking about numbers.
With semes, the majority is light haired.
With ukes, in general about 70 to 80% have light hair. So, even considering same % of atrocities committed towards light vs dark haired ukes, the % is more for light haired ukes.
Japanese, Korean and Chinese all follow this.

So up to the point I read the MC does talk about the incident in detail. He was supposed to service a guest in the crater, an adult man. It wasn't full on rape as there was no penetration but it came very close to it. Fortunately at the last minute he turned into a wolf and attacked the pedo but didn't kill him

I finished the first volume where he is still a child and nothing like that happens again. I also skipped a bit further and didn't see anything related to rape, but I'm not 100 % sure as it was mtl. Anyways I'm gonna continue reading it as characters and the story is interesting and I want to see the MC grow and become more self confident amd not be afraid and repulsed by his monster side
Trigger Warning - Pedophilia, Child r@pe, Child Prostitution, Child Abuse, Child Sex Trafficking
Damn it. Another work with sensitive/triggering content without any warnings. Disgusting.
Also seriously the disgusting adults surrounding these kids. No amount of torture is enough for these disgusting creatures.
Also, another light haired seme who is subjected to sexual abuse as a child. Hardly happens to dark haired semes. Authors have this twisted racial domination and fetishism going on where they write light haired characters being repeatedly subjected to such atrocities.
Till date, number of manga with this trope - 58 (Light haired Seme) vs 17 (Dark haired Seme). I don't even need to count this happening to light haired ukes, since the majority is written with light haired person as uke.
