The question is, do Sora and Taichi really like eachother? I'm sure they do. Listen to this quote from a digimon magazine (a 01 book). "Sora is well really okay." And right beside it, it says "My best friend, Sora." This proves that Taiora is official! Or at least it was in 01 :/

They also had a lot of times in 01 when they were so cute together ^^;; and it just makes sence! The leader of the boys and the leader of the girls together. They also love soccer and sports, so why not?
