If you don't want sex scenes (and frankly this is the wrong game for that anyways), then what are you hoping for with the inclusion of romance?
It doesn't change your current party set up.
It's not like the main characters will marry at the end and/or have babies that you can play as the next generation of heroes.
They cannot add a bonus for being romantically involved without starting a PR shitstorm unless they make it possible for every LGBQT pairing as well as your heterosexual and asexual chars.
I don't mean to sound critical but I am genuinely curious about what you want romance to bring to the game other than a few lines of dialogue?
