@the only joke here is me What the h*l? That didn't happen. You might be confused because of the R4p1ng part, but Jiwook simply doesn't remember what he did wrong because he swears he did nothing wrong. The only time he said he might have done something was in high school, but he only remembers the fighting and nothing else. So practically, there is no explanation right now for why is jooyeon is treating Jiwook this badly.
