there’s plenty of good korean manhwas, it’s a waste of time to worry or question why korean authors add rape in their stories, they highkey just wanna go viral
you should try reading this story, it’s really cute and no rape https://www.mangago.me/read-manga/emergency_youth_record_book/
Sorry to say this, but you are in a pirating site. Basically the yaoi you're getting in the yaoi genre tab has a bunch of stuff with rape because it is unfiltered. It's kind of like in AO3 where you click on the ship tag and you see noncon when you scroll. For mangago, unfortunately you can't really filter it, so you're stuck to seeing a bunch of mass produced rapey BL. Also, it sells. Believe it or not.
i think it is very telling about korean thinking and society as well. not been to korea so i can't really say anything with solid proof but it's very wierd how so many korean BL has rape or coercion. like, there must be a reason to this kind of thinking. how is it even hot? i don't know. maybe that's how their thinking is subconsciously? "they find the guy so hot they can't control themselves" sort of thing? or "i raped you bc i liked you"? i would like to know more about the environment of korean society from a korean living in korea or anyone living in korea to know the reason behind this thinking.
Take it with a grain of salt but Killing Stalking singlehandedly impacted how Korean BL moved forever. So whenever you see psychological/horror Korean BL, just remember it's probably a bootleg version of KS lol.
Also, from my observation, since SoKor is a pretty conservative country, I see it that many people read BL to be liberated that even ones with dark themes are appealing.

To this day I’m questioning as to why Korean authors are so obsessed with rape in their bl manwhas? Like is it so hard to write a sex scene that’s consensual??
