For official CCS couples, I like Yukito x Touya the best. I think it's sweet how Touya looks after Yukito so much yet at the same time Yukito doesn't want Touya to worry about him, and they would just be so hot together. Plus, I also like Touya's nickname of "Yuki" for Yukito. ^^ For unofficial CCS couples, I like Meilin x Tomoyo. There's a lot of hints that they like each other more than just friends in the episode "Sakura's Most Precious Friend" and the Sealed Card movie, even though it's not officially stated whether or not they love each other. But I really like the idea of this coupling because they seem to have a lot in common with each other, and then there's that whole episode I mentioned earlier in my post. Plus, if they became a couple, neither character would have to be alone, and we would still get a CCS yuri pairing along with Sakura x Shaoran, so it's a win-win situation for everyone. ^^
