Correction, Hajin does know Daejun is aware. In chapter 100s (I think 105?) it's confirmed on their "date" after treating Shiyeon's hands and seeing Ahyeon at the hospital by Hajin straight up thinking "even though we both know, admitting is different. The moment we go back to Hajin and Daejun instead of Shiyeon and Daejun, we'll lose."
did daejun know that sihyeon is dead and the one's in the present is his boss (?? wait
is that righ???) did daejun know that the person in sihyeon's body is his boss (i forgot his nameee) pls help me understand whatever's happening.
