I think in the original story too Yeowoon probably only got close to Seonwoo because he's obsessed with Hajin. Or Hajin put him up to it in the OG story. I can't figure out any other reason why Yeowoon would be so obsessed with Hajin, unless this world is still affected by the plot and the plot just decided to make Hajin the MC bottom instead of Seonwoo
