Man, they're all terrible characters. I guess Dagger was okayyy, and Celes is great, but doesn't really fit the criteria (she's more of a main character than HER love interest). I won't rank them, because that would imply that I like any of them.
Man, so many great FF characters, and not one of them a love interest. I wonder what that implies.
...Unless we include non-main love interests. Rydia and Celes are awesome.
