Hero Antagonist
@givemersspls Nah, it's pretty obvious he just deduced it.
First Joonwoo asked about his preferences in girls with a flimsy excuse for Sungah to show up matching those a few days later and he knows she has this ranchat friend that helps her a lot
then the day Sungah talked to him about the stalker Joonwoo was missing at watching the movie, for then the stalker stopping and succesively finding out from the stalker that another person tried to stop him back then
then he simply recognized him at the date from the tiny stature, mannerism and possibly voice
Also even if he were using ranchat it's not like he can really spy on others' conversations
@norjack2 well it seems he is sincerely annoyed by the fact that Joonwoo did objectively do some damage, as she is now emotionally stuck on a guy that doesn't actually exist, so there is no painless way out of it for her
and he was pretty levelheaded about it as he didn't want to fight him or anything, it was Joonwoo that snapped at him and became the aggressor looking like a deranged villain in some shots
