Of course Atsushi would always have warned any Agency members turning up about Chuuya being here. Maybe it's just the fact that Chuuya told him to that threw him off? That seems really counter-productive for an enemy who genuinely intends to wreak havoc! But, okay, message belatedly accepted, strange mafia person.

Ugh - Atsushi knew they were stolen goods..! But he genuinely can't waste the hot chocolate, even with that blatant confession. He's just going to be a bit more sulky as he drinks it, now.

Noticing Chuuya's direct approach a little too late, Atsushi has to decide between jumping out of the way because he doesn't want to anger anyone (let alone Chuuya - but really, anyone), or not jumping out of the way because it risks spilling the hot chocolate, which is basically a crime against humanity for wasting nutrition. Unable to decide in the time he has, but leaning slightly more towards saving the hot chocolate just because Chuuya insists on calling himself a dangerous enemy (and Atsushi probably shouldn't respect those as much as other people, even though he kind of does), he does an awkward spin, clutching the chocolate to his chest, to try and make Chuuya bump into his back, keeping his drink safe(ish).
