I was surprised that there wasn't even a hint of a romance option for Sassan, although I suppose that makes sense because there isn't an equivalent for female characters.
Making one of the optional trainers a romance option isn't really a good idea either because that means if you want to use the other trainer, you have to choose between a romance path or building your own character the way you want.
This series isn't really designed for romance options, really, what with all the death and destruction in all three games.
The closest things to romance options were both from Divine Divinity: the parody romance quests in the elf village, or Penumbra.
I thought originally it would be Hermosa for males and Kenneth for females but I guess you're right in saying this game isn't designed for romance due to the fact you can change sex whenever you like as that would make a relationship confusing
