I don’t think so. Probably he just did the same thing the pink head had done to him before. A bit of pain and he’ll be fine. That scene wasn’t that serious, I think if he’d gotten him killed then he’d have been in a bigger trouble. But they just went to see a doctor like nothing happened
Is pink hair dead? Just curious because it seemed like a big deal for Yoonbin witness him kill someone and not really register or say anything.
