I think in chapter 19 the one who messages hajun is his twin brother I think that’s why he seems so mad.i think the twin brother doesn’t show up till chapter 20 (the guy with the grey hoodie) I also think the “hajun” you see in chapter 21 isn’t him because I don’t think hajun would ask danwoo questions that would make him anxious plus in chapter 26 i also think it was the twin not hajun.
