[GOD here Kaoru is trying to actually help out by explaining things, and all the effort is flooding away into the sewers. What did he do to deserve this sort of karma!! (Everything, maybe......)

But Kaoru has a black belt in patience, so it's not like this is enough to cause any outward changes, even if the inward train of thought right now is currently like "maybe if I pinch his nose shut, he'll forget how to breathe".]
