Juheon knows what dohu went thru bc he has trouble expressing his emotions and he js keeps using that against him every single time they talk??? imo he weird asfk for that idk how im supposed to like him. Plus i rlly dont get why he broke contact with dohu in the first place it js seems forced asfk i understand being mad but allat extra shit was unnecessary
Remember how Juheon used to be? He is the type who will hurt others first before they could hurt him. It's a form of defense mechanism he has because of long history of abuse, abondament, and betrayal. Juheon has huge trust issue, so once he found out Dohu had ulterior motive for approaching him in the first place, Juheon ended up questioning if Dohu has ever been sincere. This perceived betrayal caused him to regress to his old self, not trusting anyone and would rather hurt Dohu first before he himself could get hurt. Still, as you can see with his reaction from Dohu getting hurt by hot water, Juheon still deeply cares for Dohu, but his past trauma and Dohu's inability to convey his true feelings are not helping his case.
i dont like hate him but i do get sad everytime he uses his issue with emotions against him. its not like dohus constantly insulting him by bringing up his people pleasing personality to insult him.... Its just so tough to read because dohu finally was understanding his feelings and then boom he finds out and it goes to shit lol

Dohu's flinch at Juheon calling him out for not understanding emotions HITS HARD. Juheon literally taught Dohu he that he does have emotions and now he's just throwing that back in Dohu's face. IT HURTS SO GOOD.
