I love Kanade. I know they're cousins, but I like him with Saku way more than Chihiro or Yuuri. He's way more interesting, and he's the only one that makes me laugh. Plus he obviously cares about her.
And before anyone gets after me for the cousins thing, let me remind you that in Fruits Basket, everyone was dating their cousins, and nobody thought twice about it. (kyo and kagura, hiro and kisa, haru and rin, shigure and akito) I mean, I was actually surprised that no one seemed to care that these people were all related. But whatever. So i don't see why KanadexSaku shouldn't be a possibility.
