What?
Cloud doesn't seem to have much a relationship with Tifa even after VII and after the events of Advent Children, I don't really see a relationship there other than being good friends. Squall and Rinoa were just okay and a little forgettable. Zidane and Garnet would have to be my favorite since I'm such a nostalgic guy, but I do think that Tidus and Yuna had a connection that seemed right for each other.
