Yahwi practically raped Jooin while he's drunk but ok
He just laughed it off when Jooin asked about what happened but ok
He treats Jooin like a prostitute but ok
He isn't aware of Jooin's feelings but does he have to be an asshole? Ok
He doesn't clarify their relationship and just fucks Jooin and leaves but ok
He has a tragic backstory? Who fucking cares
He raped him??? Ha? Are you serious? He wanted it first. Jooin started it. And when he found out that it's "ouch" he said stop but it was late. And it was first time it's always "ouch". But ok
Yes he laughed but also he can thought that Jooin just made fun of him.... but ok. We always see only Jooin point of view but we never ever read what's happening in Yahwi's mind. So how you can judge someone without knowing his reasons? No offense but everything has two sides.
Prostitute?? Yahwi told that? You don't know him he can think that this is normal because his previous relationship was always like that. You never know... but judging is easier than thinking.
He DID EVERYTHING WHAT JOOIN SAID TO HIM? Ooo, no way. And money? He probably has bad feelings so money for a cab it's okay.
But you forgot the most important thing - Yahwi did what he did and Jooin took all of it without hesitation. He has feelings for Yahwi but basically he never asked him clearly about anything. He wanted spend time with Yahwi - he got it. He wanted sex - got it. He wanted something else but never told him - his fault.
That's rape. He's drunk af. Jooin might wanted it but does Yahwi have to take advantage of that fact? Look at you defending his actions. His tragic backstory has nothing to do with rape. Rape is rape. Reread the fucking chapters again. And wtf when Jooin asked what happened because he didn't remember, what's the first thing he did? He laughed.
JUDGING WITHOUT REASON? Are you blind or what. Ok wait, I'm going to link you the pages since you're blind lol

Okay. You know they have some kind of relationship but they don't talk about it. Well that's normal in mahwas. So both have some feelings because Yahwi doesn't look like someone who just go out with everyone. He looks cold but he has something in past. We don't know what is it yet but we'll see. I don't think he is bad. Why? Because he goes whenever Jooin want? Because he has sex with him? Obviously Jooin wants sex too. But what is the problem is that he wants also feelings. But Yahwi is careful probably because of his past experiences or whatever made him like this. But I don't think he does Jooin something bad not from his point of view. Joioin didn't tell him how he feels or what he wants.
