Wait. Are you not able to get hearts with anyone else once you have 3 with someone?
That would explain a lot. I just figured 2nd and 3rd heart was only implemented with Bernard. But apparently it's just my choices.
nonono. you had it right the first time. you can still get more hearts with others once it is implemented.
no the thing thats bothers me is that you are forced to romance are certain character in order to finish a quest-line that rewards you with another cool character that you otherwise wont get. and the fact that caleb treats you like Bernards new boyfriend didnt help.
