Yohans dad is catholic and his whole family outcasted him for being gay and it’s clear he has really bad trauma from it. They don’t take pictures with him, his dad constantly talks down to him, and they exclude him from family events like family dinners. Kang then essentially made him have dinner with his family and when Yohans said he didn’t want to Kang insists to Yohans father to make them both plates.
Then Kang acted like he was dating Yohan at the dinner making his dad think Yohan and Kang are dating meaning Yohans going to get more hate and backlash from his family which is the last thing Yohan wanted because of his trauma. He’s mad at Kang for not listening to him and making his living situation worse
As someone who came from a Christian family coming out as gay was so traumatic for me and still causing me depression to this day and I only date the opposite gender to keep my family happy. I really hate Yohan for how he treated Kang but I can only imagine how shitty Yohans living situation is and how much worse Kang made it. This however doesn’t explain away his shitty actions he made those himself and his trauma doesn’t allow him to traumatize others.
Yeah, Jun was bad for assuming many things and working on his own without considering or consulting anything with Yohan, because his actions were objectively shitty and kinda self-centered, but he did that because he loves Yohan and wanted to help him. Yohan on the other side is a just spoiled little teenager shitty brat, that didn't understand the true reason why Jun did that and do what he did becauseof that (it was of course a horrendous thing to do, but it was in line of his behavior that we seen so far, Jun wasn't surprised that Yohan was capable of doing something like that he was surprised, because he didn't understand why what he did was wrong and why Yohan aggressive behavior was directed toward him). The whole problem with their relationship is that, Jun kinda refuses to acknowledge that Yohan is just an immature brat and constantly puts him on the pedestal. He acknowledge that Yohan has shitty personality, but all their conflicts starts because they both have big inferiority complex and refuse to talk honestly about their feelings to each other while being jealous about each other af. Jun just kinda think his feelings are something bad, he feels inferior because of them and is toxic towards Yohan by being a freaking tsundere who also feels better by knowing that Yohan kinda likes him but refuses to show that he likes him back. What Yohan did was fuck up, but he really is mental and Jun don't really think about how things looks from Yohan's perspective. We know what Jun is thinking because of his narrative, the only feedbacks Yohan is given is a poker face and crumbs of affection from Jun.

Wtf???? I haven't read this for a while but why Yohan being a dick
