For fucks sake where is skylar!? My heart cant take it anymore!! And someone can pls expla...

I think what happened was Jung goo beat up yeonduk and the counselor found them. Then when Skyler found out about it, he went and beat up Jung goo and they were found by some teachers and Skyler got suspended. Of course, Yeonduk didn't know that Skyler avenged him. (●'◡'●)ﾉ

I think that's my understanding too, but in the other hand I still not sure if my understand is the same as everyone else too.

Didn’t mean to downvote
