I'm starting it now and just a few chapters in I KNEW it was gonna turn out how you're describing. I literally thought to myself "pls author, don't make me like Minwoo only for him to stay a 2ndary character who has to deal with the main characters being complete idiots all the time".
Idk if I want to continue the story tbh..

Minwoo is the only character that I like in this along with that brown-haired HS friend of ML. At least, Minwoo has a knack for communication and is very perceptive. He does the right course of action when he gets the narrative of both sides.
Glad he was tactful enough to follow MC when he went to a street he never voluntarily went to before. He has seriously been a green flag aside from his obsessive tendencies but even that was dealth with bc he was able to accept MC's answer and keep things platonic.
Joohyun is so dumb following people left and right that it's so annoying. He puts himself in danger and then pulls the victim card when something bad happens. I would rather see Minwoo and Seojoon's dynamic ngl.
