Because its weird to promote rape and sa on a "romance" novel. Not only that but theyre ppl say things like "bro its js fiction its not real" when theyre are literally stats and reports in every country of actions from fictional activity being translated into real life. (Its for the same reason ppl have their kids watch like...mlp and sesame Street as kids to give them alternate perspectives on how to interact irl) not to mention it brings bad rep to the gay community which theybve asked multiple times to stop promoting. and ppl tryna ignore n be rape apologist instead of acknowledging that this shit is weird is genuinely sick man. Not only can u tell a dark n multi dimensional story w/o assault, but tryna advertise as a plot device n a "yaoi" is js bad writing n horrible case study n embarrassing for the author. Thats typically why it gets criticism.

Idk, people are always complaining about rape and SA on manhwa but they continue to read it? Why are you here if that's not what you're into? There are a bajillion happy, fluffy manhwa for you to read. No need to downvote this one if it's not your cup of tea. Clearly there's an audience for it and you're just not part of it and that's okay. We don't have to be involved in everything.
Anyways, the scenes in this manhwa are great as is the art. Only detraction is that it's (again) painfully obvious that this will never actually be a poly relationship. I swear there's barely any interaction between MC and the other guys besides ML. Just a few here and there and then throw them all together for a nice party. Authors are such cowards. GIVE ME A MANHWA WHERE HE CHOOSES THEM ALL. Overall still a good read, just keep in mind it's another poly bait and switch (but aren't they all?).
