Romance is completely worthless if you choose the dialogue of more than one protagonist. For the sake of immersion(not feeling like I'm playing the game by myself but with a companion that may disagree or agree with some of my choices on their own), the game should have an option to make one of the protagonist AI controlled. I don't know what they were thinking. Majority of people aren't going to play co-op.
The finished game does have an option to have AI pick the dialog choices for the second protagonist.
