Squall since I don't know trout about the other guy.
Isn't that the whole point of his character? He constantly pushes everyone away, then realizes what an idiot he's being and what he was doing was wrong, and learns to get close to others. That's part of his character development. I can't confirm since I never finished FF8 but it seemed to be the kind of direction they were taking his character, and I'm also basing this on what other people have said.
