The only two that really focus on love are VIII and X anyway. Some others have nicely developed fluff, but it's nothing huge. Zidane and Garnet have a nice love thing going, but it's not the main focus of things...But I'll give IX a "maybe" to keep everybody from chewing me out.

So there's really not a love story, but there's still plenty of drama to be swept up in I guess. And I also found the plot to be surprisingly straightforward.
