The ML is a sweet heart and Minwoo WAS being obsessive. Its understandable tht he was worried because of the childhood incident but trying to controll everything the ML does and even beating the guy up was crazy. he was basically following him everywhere and yelling him who he cant see and where he cant go and although he IS caring the ML has voiced tht he would like Minwoo to simply give him space and stop "worrying" about him and basically let him live .
Minwoo defenders are so blind to his red flags smh. He’s controlling asf and he even blatantly stated how bad he is TWICE. He controlled who mc was friends with and who mc met since chapter 1. Mc’s sister isn’t as overprotective as he is. He’s not pure at all. He is fully aware that his overprotectiveness comes from his hidden intentions and for his own benefit to get with mc.
You don’t know how icky it is to have a male friend you have no romantic feelings for, doing crap like that.

Only likeable character here is the sister and minwoo, i hope minwoo gets to find a lover as pure as him, the rest mc and ml can fck themselves looool
