Actually nothing's wrong with youngwoo. He just love the 2nd ml too much. That might be his mistake. He didnt manipulate him but rather took advantage of taejoo's longing and pain. This is a great story where they're all victim of their foolishness.
I'm a little loss here, but the thing youngest wanted to come clean abt was how he insulted Yoon right? Or did he cheat or smth idk
He told taejoo raped him so they can be together. I agree with everything you said except that nothing is wrong with Youngwoo. Imagine thinking you raped someone the guilt and shame taejoo feels when he didn't even do anything. You can tell from the chapter how guilty and bad he feels for the rape that didn't happen.
I think for everything he did
He wanted to come clean about how taejoo didn't rape him
Actually, it's a great story cos they can all justify their emotions but that little motherfucker youngwoo. Yoon gave you a chance and you didn't come clean to taejoo and now you've caused unnecessary guilt for taejoo when you're the one who should be feeling guilty for manipulating him.
