Nono dw about it, you're good. I honestly don't think it's at any specific point, he does recognise firstly from his finger movement habit, then the ad as being the cold loan shark and i believe him just being able to contact daejun and wanting to specifically find out about 'himself(Sihyeon)' which is already odd but without actually fearing daejun too. I think during this time, daejun was still confused but with gradual interactions, i think he had solidified in his head that it was indeed Hajin. So somewhere before the first like the car kiss, daejun must've solidified his doubt

chapter 35! thats when he found out for sure that he is hajin bc he started talking about the trip. in chapter 39, daejun interrogated the dr in a flashback that happened b4 chapter 35 and was almost sure that sihyeon was hajin, but he thought he was being delulu bc its a crazy concept. also in the novel, right after sihyeon left the bar (restaurant?) he went to go check the security cams and saw sihyeon walk straight to the room he was in, and apparently that room was a place only he and hajin knew abt.
Does daejun already know that sihyeon is hajin or not?? I know daejun is reminded of hajin of sihyeon but does he know that its hajin in sihyeons body ?? im so confused plz help
