Wouldn't that make Seonho the bad guy? I mean Muyoung doesn't have a boyfriend so of course it's no problem for him but Seonho doesn't know that. He thinks he's in a relationship and didn't ask whether their relationship is open or not. He was too afraid to ask, because he knew that it could ruin his chances of having sex with Muyoung.
In this case, Muyoung did nothing wrong while Seonho slept with someone in a relationship while being completely aware that what he did was most likely not okay.

Personally I don't think so. I think both of them did wrong. It's wrong of the person in a relationship (even if it is a fake one) to initiate sex with a person other than the lover. Of course Seonho shouldn't have let it happen, but Muyeong being in a "relationship" shouldn't have started it, or at least claimed that he was in fact dating someone already. They're both in the wrong but I think Muyeong did worse.

But what exactly did he do wrong? He's single and was very upfront about his intentions. He didn't cheat or anything. You can blame him for lying but you can't blame him for anything else since that relationship doesn't even exist. You can't cheat on a boyfriend you don't have.

But he left the impression that he had a boyfriend onto Seonho and still had sex with him. I understand why he lied, but he shouldn't have lied about having a boyfriend and then initiate sex with another man. That's all I'm saying. I do think Seonho should've stopped if he knew that what he was doing was wrong, but I also think Muyeong was also in the wrong.

You're all thinking too much. The two of them didn't give a shit about their "wrongdoings" when everything was cleared up. It was never mentioned again.

But why is this worse, that's my question. You wrote it's wrong for him to initiate sex because he's in a relationship, even though it's a fake one.
I just don't see why pretending to be in a relationship and having sex with someone is worse than having sex with someone who's in a relationship.
I personally think that nobody did anything wrong (they did something stupid and I don't like the lying part but Muyoung is single and Seonho is not cheating on anyone) but I don't understand why some fans are shocked by Muyoung's behavior but what Seonho did is not that bad.

Of course not, because there is nothing to discuss anyway. Nobody cheated and nobody broke up a relationship or anything like that because there is no real boyfriend.

You can ignore my reply. I'm not going to be online for the rest of the week and I don't think I'm invested enough in this topic to continue it next week.

Sorry I forgot to reply;; I suppose you are right. I reread all that we've both written and I do realise that it wasn't really a topic worth discussing because they both had their reasons. I get it now :')
