I can't deny that this manhwa is fucked up 100%, but on a plot level, this whole deal of a bullied guy taking revenge of his bullies and rapists doesn't sound too bad, could be an interesting psychological horror story. If only it wasn't basically fetish content. There was a way to show the characters' trauma, and the sexual assault and rape scenes and how it affects them, without it being so graphic and fetishy. The whole manhwa just looks like the author had a wet dream about rape and made a rushed plot to have an excuse to draw it all and put it into a manhwa. It's irking me the fuck out. Also tagging this as "yaoi" is crazy when it's just a bunch of sexual abuse, which proves more than this is basically just fucking fetish content for preteen fujoshi girls who will read anything and everything including graphic rape for sexual gratification.
I finished the drama (it's so short, only 5 episodes for what...) and searched up the name in hope of there being an original manga, which it had. I'm excited to read it !!!
