people like to pick apart stories while ignoring major plot lines just cuz "they don't care about a characters back story", on god people hate character development I SWAER. dudes had trauma since he was a kid which explains a lot of his obsessive behavior it's obviously not a excuse but it sets the bare for his characters personality. you're right though he needs therapy and to learn how to be in a relationship
I know he's guilty but it surprised me that a lot of people still don't understand why he folded as soon as he saw Won Dae like that. Dude has legit ptsd and people still think it's just his pride going on here. What's the point of the author putting it in the story if people aren't going to pay attention to the story. He really needs therapy on top of learning how to be in a proper relationship.
