I support this couple and part of this reason is that I live in the U.S. and I only found out about Card Captor Sakura because of Cardcaptors, and thanks to the Internet, I was able to find out that Cardcaptors was dubbed and even though I didn't see any E&T pairings, I figured that it was cut out of the show.
When I finally saw all 70 episodes, 2 movies, 3 ova's, and the Kero-chan omakase from the 2nd movie, I was genuinely surprised that there wasn't any E&T pairing in it, so I told myself that they might have it in the manga, but I read all 12 volumes of manga and they didn't have it in there either, but I was so influenced by fanfics with this pairing, that it's hard to persuade me otherwise. Even if it's not official, fanfiction.net is what brought me to like this couple. I will always like Sakura & Syaoran first, but Eriol & Tomoyo will always be a very close second!
