Fujin and Raijin just wouldn't make any sense. Fujin's the thoughtful quiet one who only speaks when she's got something to say and Raijin the clumsy goof. Can't see what would make Fujin go that crazy. And to me it seemed obvious in the game that she was in love with Seifer. [no, I'm not suggesting a pairing there, Seifer should only be with Squall]

And ZellxSelphie doesn't make any sense for the opposite reasons. They're too much the same. IrvinexSelphie may not make that much sense either, but I'm gotten so used to it that I don't care anymore
