It probably and most likely has to do with the lesser evil. Cain never purposely hurt, humiliate nor made Jooin feel less of himself. It's probably why people like him despite some of his actions. All of them have flaws and have their gray areas but you can't help that most still like one with a bit more 'morals'.
Between him and Jooin. Cain knew what he wanted so people like that he was more decisive (even out of the three). He never "strung" or gave Jooin false hope. (Ppl have been saying Jooin been doing that to both)
But people calling Jooin toxic has been happening way before endgame from both teams equally. It's nothing new. He's always been hated for no reason.
Now ppl still say that because his development of worth went away. And I seen all sides say that, even some of the winning team. Some preferred Jooin to stay single because it made sense to leave both toxicity.
I'm not a Cain shipper but I've seen Cain fans acknowledging his behavior, although what seems to matter in this comparison between Yahwi and Cain is who made Jooin more happy. And I think we can all agree Yahwi hurt Jooin throughout most of the entire story and Yahwi did things way worse than Cain. It's honestly no wonder he's getting the most hate.
An example on why, would be that Cain most of the time apologizes right afterwards for his actions. While Yahwi and Jooin barely do until very late. Cain is able to realize his wrongs quickly and be expressive without giving false words unlike the other two. That could be why he isn't much hated here.
Also, looking at the replies should give you a simple answer too. The first reply explains a perfect why and even a neutral reader sees it.
Yet the rest, who I assume are all on the same team, aren't giving examples but throws and implies insults. This has to also do with how each team acts with other readers.
Have to agree that's definitely not dub-con. Dub-con is when the consent is dubious, and when readers can't tell when a character involved is certain about whether they wants to participate. In this case Jooin did. Cain asked "if you don't want to, push me away" which Jooin didn't. That to readers told us Jooin gave consent. Then when asked again Jooin nodded in agreement. We readers saw Jooin answers from his actions. Nothing was dubious. We didn't see Jooin stay quiet and let Cain decided own his own. We saw Jooin indicate his answer.
do you know the difference between being sad and being drunk??? there's your answer. being drunk means he was literally not in his right mind and under the influence, as well as barely even awake. cain never forced himself or told jooin let's fuck right now or else. at least he asked for consent and jooin was awake, sober, and in his right mind enough to say yes or no. are you actually comparing raping someone drunk to having sex with someone who's sad??? you need help.
No but like do these people not know of the 4 types of sexual manipulation - verbal coercion (argumentative persuasion), physical force, financial coercion (blackmail/bribery) and EMOTIONAL MANIPULATION (exploiting someone's emotions).
I thought they'd at least be educated on the issue of sexual abuse considering how much they like to talk about it smh

... have a problem with all the abusive and problematic stuff Cain has done? He stalked, sexually harassed a sleeping person, constantly lied, and engaged in dub-con sex (using someone's most vulnerable moment to push them into sleeping with him, fully knowing they're in love with someone else).
Like all 3 of them are honestly written so toxic, so why do they act like it's only Jooin and Yahwi? Idgi
