Woah the fist fight. For Jun's sake (I guess). It looks like that Satoshi might want to confront Sho but then Sho got angry and lash out at him and then things got physical? Or that Sho being jealous at Satoshi and confront him? That's what I like to think anyway XD
Anyway Jun doesn't know why Sho and Satoshi despise each other. Ah ignorance is a bliss for him. It's better for him not knowing
