[Kaoru does kind of understand it, at least! As in, it's something that's easy to understand on a technical level even if Kaoru has pretty much no real actual understanding. As far as he's concerned, it's just Oona being quirky and weird and Oona-ish, worrying like this.]

Thank you for that, then. [Seems like an appropriate response, anyway.] I'll certainly do my best to stay safe so that you don't have to worry.

[A REWARD, THOUGH. That sure would be nice, but Kaoru is certain that this impromptu camping trip is the reward...]

I hope it ends up being worth your while, in any case. This experience is certainly what some would consider a hassle...
