Is this comment actually real
whoah... im just going to go out on a limb here and say you are korean?
First of all, u can't really blame MC cuz he grew up being sick and lonely so meeting a person who was in the same circumstances as him, he can't help but feel a sense of camaraderie with that person. It just happens that person might be an asshole and he didn't even know. Furthermore, they're not even in a relationship. It was ML who proposed to be fuckbuddies and MC has already been doing his best to hold back his feelings. So wtf do u expect MC to do he genuinely doesn't know that there's supposed to be a specific person he shouldn't interact with lmao.
The only person to blame here is the instructor trying to ruin ML's life through MC.
People like you irk me you need to understand what labels are. They are not in a relationship. They have sex together that’s it lmao. Don’t get it twisted and think ML has some type of authority over him because he’s fucking him that’s where you’re getting confused. Don’t let your ship blind you from you know actual reality. Of course he clicked with the brother they both were sick as children and that shaped who they are today. He can click with anyone and even go on dates With anyone
MC just casually saying he "clicked" with another guy, happens to be ML's hyung. And MC looking all cutesy in front of him. Yep, recipe for disaster. Just be with him then and see him for what a real asshole he is. ╮(￣▽￣)╭
