I have a suggestion that you may already have plans for, but can you make it to where depending on your choices in the main story leading up to the free roam. It will give a heart AKA LOVE to the character that you chose to stay with. I found it jarring when Oliva refuse to tease, and BJ when she literally did it in the main story XD
Overall great game, and can't wait for more hopefully very soon! :)
