Eh? Isnt Chappu Wakkas Younger brother?
But anyway i Love Wakka/Lulu far more than i like tidus/yuna, mainly because Wakka/lulus love story wasnt mentioned that important in the plot and developed far more gradually than Tiduna - which was kinda like love at first site - which i normally like - considering Cloud/Aeris - but Tidus just BITCHED about it for AAAGGGEEESSS!
But meh. I only like Tidus and Yuna because Yuna is Awesome in FFX.
i dont wanna count that *other* game as canon as they both suck in that game.
