It’s not as simple as u think, incheol did consent but its still sexual coercion. Incheol is going for extreme lengths for his goal for them to give up the gym that hes willing to consent to an incredibly painful act. They both consented but it’s more of a representation of how messed up both of them are
i think what readers want is enthusiastic consent, which is not whats happening in this situation. incheol technically did consent to doing it, did he want to? no but he HAD to, to get pyeonghwa to agree to giving up the property. incheol is desperate and pyeonghwa is using that to his advantage to get incheol to agree to doing sexual acts with him. adding on to that, pyeonghwa seems to enjoy watching incheol in pain thats why he didn't prep him. incheol could've stopped him but he would lose any chance in getting the property so he didnt. idk if we can call it rape, but its def not enthusiastic consent either, i think its more dub-con
again, coercion is not consent. if he did not want to, but had to, then he did not consent. if anyone is using anything to their advantage to get another to agree to sex, there is no genuine consent, there is coercion. u can call that rape, because rape centers around its lack of consent. dub-con is rape majority of the time. this cant be called consent. if there's something stopping him from retracting his permission, then his consent isn't genuine.

I thought that they were both consenting adults?? sure it could be dub-con but at least its not rape? im sure they both knew that it is only for the gym.
I think that the incheol and pyeonghwa do not have a structured relationship whatsoever and of course there would be no prep. Prep is absolutely necessary when doing anal but dont forget that this is fiction. In the panel where Incheol is passed out, there is no tear seen just redness and most likely swelling and/or irritation.
Readers are definitely allowed to be dissatisfied or just overall disappointed with this chapter/scene, but going as far as saying the author didnt try or rushed this chapter is pushing it in my opinion. Lots of people are just saying that the author should do better and that they wanted a more in-depth, proper sex scene and I want to know if anyone is willing to expand on that/their opinion. I too am a little disappointed that there was no prep and that incheol passed out, but i expected it and was happy with this chapter overall.
