I've been waiting all week for this update and it was over in the blink of an eye but it was so good and unexpected. I wonder if this is the first time Sho has hit Jun or any of his siblings for that matter. I don't like violence even if it was just a slap so I can't excuse Sho's behavior but I think Jun went overboard with his joke, vengeance or whatever that was. I'm dying DYING to know what is making him behave like this.
At least we got to see a different side of Kazu and I like how caring and supportive he was of Jun. He's such a softie underneath all those snarky remarks. ;p
