For American standards, Touya and Yukito's relationship in a children's cartoon may seem "weird", but this is "normal" for Japan. Lots of anime have homosexual characters in them, even children's shows like CCS. The difference is in our cultures. Japan doesn't have as many "soccer moms" as America does, so they can have stuff like that in their children's shows. So, if you're going to be an anime fan, you'd better get used to seeing stuff like that because homosexuality is in quite a lot of anime.
