Kang Jun played the victim card so well that almost everyone here failed to see that he's not that good of a person to begin with. He befriends people with selfish intent, he puts up an act so he can remain relevant and respected in social circles, he's as shallow as he claims himself to be and sees only what he wants to see.
I felt bad for him at first about what happened between him and Junwoo (that fucking asshole). Then once everything went to shit and people were bullying Taesan, he spoke up only when he thinks it's the optimal time for him to look like a good guy and only because he believed Yohan would back him up, boosting his social status.
When he was at Yohan's family home, he assumes that he's doing a good deed without thinking. He just assumed shit, thinking: "Yes, I'm FINALLY the person above Yohan, holding out my hand to someone so helpless." When Yohan freaked out and showed that he hated what Kang Jun did (doesn't excuse Yohan's aggression but only those who lived their whole life with a shitty family like that would understand the rage), all Kang Jun thought was "Oh I did something good but this is what I get, oh my feelings, oh poor ME. ME ME ME!!!"
He's pissing me off.
Out of all the chapters, I enjoyed Cheolho's backstory the most. He's not even a violent child yet his parents gave up on helping him as if he's an uncontrollable psycho or something. He directly asked for help, he tried to be what they wished he was, he just wanted to be loved. I personally think he deserves better than Jintae. If he had a better environment, he could've been a green flag lover.
Jintae clearly has some internalized homophobia. Probably why he's okay with this relationship once he got a pussy. But the speed in which he goes from "FUCK CHEOLHO!!" to "I'm in love with him, I need him with me." really threw me off. Even back in highschool, his "love" for Cheolho is so shallow, I can't accept it as Jintae being too in love to hate Cheolho.
