[this one's fine..... buzen is still on edge and itsuki can probably feel that - the way that he hasn't fully relaxed and probably won't as long as they're on what he perceives to be a mission.

despite this, he looks relaxed. his grin is easy-going and friendly, and the only sign of tension remains only at itsuki's touch. despite his head being empty, buzen is a good improviser.]

Oh, good to meet you, Hei-san!! Sorry - was that your ball? I can get it back for you if you want!

Guess an instinct took over there.
