Kaoru just hit Kenshin because she accused him of not liking her food. on a note Kenshin is too polite to complain about her bad cooking even if he didn't like it though she has accused him and hit him for it before.
This one has put a lot of time and effort in making this one look as perfect as possible, that this one has, and this one thinks you should vote on this one, that you should. ^^x This one likes how Kenshin talks. ^^x
