Squall for obvious reasons. He'd be all romantic like "Hey...let's go kill some things in the training centre" then he'd level up and give me a back-bone crushing hug while patting my head with his grat blood stained gloves and ask if I'd feel like to go back to his room...to show me his collection of assorted gunblades that I may look at but never touch. Then he'd surprise propose to me with a ring with a big-ass sapphire (diamonds are overrated) because we all know Squall is rich af, and then I'd say yes, and he'd smile while Quistis's audible sobbing could be heard from somewhere outside the room. Much romance. Very woo. Wow.

Anyway, he seems like the very least likely FF dude to cheat on you (Cecil as well but Cecil is prettier than me) soooo yeah. Squall I choo-choo-choooose you~

Now for ladies I second Lulu and Yuna, Lulu because she's cool as a cucumber and Yuna because she so darn sweet :x
