Hopefully Kaoru will learn that the words out of Nai's mouth don't often have any deeper meaning, certainly not purposefully. He speaks his mind as soon as something pops into it, for better or worse.

He doesn't understand what Kaoru means by 'improvise,' but it's probably more important that they'll be helping each other. So he nods a few times and has his wings unfold in the same fashion (after several seconds of trial-and-error) before tightly gripping the other boy's hand.

"O-Okay!"
