I'm not going to watch that. From the pinned comment alone I can see she doesn't know what she's talking about—she says that Koogi, the author, has said that KS isn't a BL. That is false. In the stories first Q&A, which you can read for free on Lezh!n, Koogi calls it a BL. It's classified as a BL on the site it's published on and within the story itself, the author calls it a BL. It's a BL, simple as that. You not wanting to acknowledge it as such doesn't negate that it is.
What's your point? A straight seme is quite literally a hugely popular trope within BL to the point people completely write off BL due to it.
Also, during the last author Q&A, which is the last chapter as you can check for yourself, Koogi is asked "Did Sangwoo love Bum? When did he come to realize his feelings for him?" to which Koogi said, "You'll know the answer if you read the final episode." And in the final episode, literally the whole reason why Sangwoo dies is because he wouldn't stop calling out Bum's name. Read between the lines.
You're clinically insane if you call that love. Yoonbum developed stalkhome syndrome like other victims of kidnapping. He was raped, tortured, abused, etc. This isn't some fucking yaoi you're actually sick in the head. This is why people call us fetishizers because people like you think shit like this is some romance story when in reality it's a disturbing and graphic story depicted of a murder and stalker.
This isn’t a yaoi manga
