IRL we have people trying to romance AIs that aren’t half as clever or independent. I’m not saying that a human-droid romance would have to necessarily be portrayed as a positive thing (it might very well violate established ethics in-universe), but it would make sense that in a galaxy with trillions or quadrillions of people, there are a few that fancy a droid.

And manumitted droids do exist, so it doesn’t have to be a master-servant sort of deal either
