i'm sure he knows, he meant to hurt jun, yohan just has his limit, he ignored jun for minor injuries, but when jun got to the hospital yohan got worried and waited for him to wake up. Yohan is a bad person, just better than jungwoo, i think that's why author made jungwoo beat jun senseless before, so yohan looks better because he won't go to that extent

Anyone who's read the novel, please enlighten me
Was Yohan really unaware of how much influence he had on everyone and how things ended up? Did he genuinely not realize that Jun's injury was partly caused by the way he acted?
I've reread the novel a couple of times, but I still can't tell whether Yohan was truly clueless and that's why he never apologized, or if he knew all along and was just pretending.
