Maybe he said Kim Dan grandma died or something so he left?

Thats definitely that

Yeah, the story has been hinting at that for a while now, I thought they were saving it for J big asshole moment. I really though the climax would come several chapters earlier though. We will now get J character's arch, and why he's such an ass, I guess it has to do with the bald dude. I don't think Dan will go to the actor dude but I think that would really rub salt on Js wounds and I would love that
:D

I think the coach made Kin Dam leave , because of what happened to avoid more tantrums from the idiot , because they didn't know if he was spy or not till now or that he did it on purpose , from the way Potato and the coach said those thing.

Period ┑(￣Д ￣)┍

I just saw the next chapter is the last of the season, damn, it will be a huge cliffhanger. Weirdly enough, I want J to truly suffer, but not to lose a match, he's good at fighting, probably the only thing he's good at.
