I’m unsure if you still needed reassurance on this, but it was in fact just a dream. I think the scene is more representative of the shift from haekyeong’s feelings for kwonyeong, to his feeling for kwonlim. His dream replaced his friend for his friend’s brother, basically.
Guys I'm on chapter 8 can someone tell me if mc actually got raped or if it was just a dream (I don't wanna waste my time on bs)
