i fink dat Touya and Yukito are just best friends, but then again their connection with the clow cards do form an interesting relationship... the lest to say
Possibly... but I think that it is more likely that, at some point in the series, they do become more than friends. It is fairly obvious, anyway, from the way that they act that their feelings torward each other are not entirely platonic. But Yukito also admitted (at least, in the anime series, I have not read all of the manga) to Sakura that he is in love with Touya, but at that point, was uncertain how he felt about him. Sakura replied that she was sure he felt the same way, since he gave up his supernatural gifts (including his ability to watch over Sakura) in order to save Yukito's life. I don't believe that it is ever absolutely clear whether they become a couple or not, but I believe it is fairly safe to assume so. Particularly considering the fact it was CLAMP that created them. ^^;
As for Tomoyo and Sakura... well, I'm not entirely sure what the original question was, but I'll give my opinion on them, anyway. Tomoyo's feelings for Sakura are obvious, particularly after some subtle comments that she made to her. But Sakura does not return her feelings (nor, as far as I know, is she aware of them), and Tomoyo knows this, so she supports the relationship between Syaoran and Sakura. Sakura's happiness is more important to her. Tomoyo was my favourite character of Cardcaptor Sakura for a long time, and she still remains to be one of my favourite characters, so I am somewhat saddened by the fact that her feelings are not returned. Even though she says that her happiness is Sakura's happiness, I find it hard to believe that she never feels sad or disappointed about it. However, I think Sakura and Syaoran are good for each other, so I wouldn't have it any other way. I would just like to think that, eventually, Tomoyo will find someone who will love her as much as she loves him/her, because she definitely deserves it.
