Please don’t call this a yaoi, it isn’t. Koogi as asked people to stop calling Ks yaoi. It’s disrespectful and wrong.
This is a manhwa that’s it. Not BL, and not yaoi.
KS is really an amazing story. I’d you’re too soft hearted I suggest dropping this, as it is disturbing. If you want “hard core yaoi” then you’re reading the wrong story. Search in tags ‘hardcore yaoi’ and you’ll find stories to go with your interest.
If you decide to read this, just remember to not pick sides. Don’t read and put yourself in yoonbums perspective. Read as a simple bystander. It’ll be easier to read that way.
Btw, this doesn’t have hardcore sex in it. This has regular sex, the story is just messed up. If your looking for messed up yaoi read Haradas work. Harada has TONS of hardcore yaoi stories.

Here’s a “hardcore yaoi” by harada:

Also here’s a tag to look through:

I have been contemplating whether to read this or not. I am exploring hardcore yaoi but I'm still a chicken. Help me decide before I invested my heart and time
