Akihiro's not wrong. The agency had given them all a briefing on what to expect of their bodyguards when they started working with them and it included a part about professionalism, but Mitsuki's gotten used to living in the dorm with the other members. Professionalism there means not killing each other but after that, and especially where friendly contact is concerned, the limits are pretty much theoretical. He knows it ought to be different here and it was, for a while. Mitsuki's not too buzzed to know that whatever boundary existed a few hours ago is crumbling fast but he just doesn't care.

"Haha, nope! This is all from the mean streets of Ginza! Hiya!" He steps back and throws a straight punch forward into the air, cradling his glass in his other hand. He's got a strong base when he does it, and chances are it'd actually hurt pretty bad if it connected with anyone, but there's a roughness to it that belies his complete lack of training. Sure, the punch would hurt the target, but with the way Mitsuki locks his elbow means there's a pretty good chance he'd be hurting too.

That's what he gets for trying to show off. Mitsuki's not sure what kind of training, if any, Akihiro's had, but he wants to prove he's more than just a cute face.
