Well, I don't really get it why people hate chunwoo. The red hair dude basically destroyed his life. I mean he didn't give a shit about chunwoo's feelings for ten years, and chunwoo was on the verge of a depression because of this fucker, they are criticising chunwoo for his last fuck with this guy, but whenever the red hair guy got horny he would come and fuck chunwoo. In the end in my opinion the red hair never liked him or he wouldn't tolerate chunwoo getting fucked by Ho in.
He was just giving chunwoo false hope this entire time not ending his relationship with him
