Joon's not a bad kid just a very vivid imagination. He has said he comes here to get his rocks off and release tension and that is as blatant as his purple font. He uses this place to pretend anything he wants. Like the child with his little imaginary friend, it is fun for Joon like a form of escapism to create this alternate reality where he can fantasize that he is a rippling hulk with unbelievable feats of strength and athleticism. I don't rip into him for doing this because it's harmless and I don't dislike the fella for whatever reason. Also makes for highly amusing banter with all you guys going back and forth and bursting his bubble over and over.
