I recently tried reloading a previous game to see if the threesome was possible. It's not, the roommate was asleep. Then I was able to visit my best friend again and talk about sex because, surprise, the roommate was not there. This is not meant to be a criticism since I love the game, but my suggestion would be that if relationships are implemented in the future, this is contemplated. Especially because this trans girl I'm dating, my best friend's roommate, she initially claimed that she didn't want any ties. Now that her romance with me has increased, she gets discouraged every time I smile another girl during our dates. My best friend does the same, by the way.
