I agree that it'd be nice if the map would show who you can meet and at which time. I spent alot of my time searching for people when nobody was even available and I can't imagine how that will turn out once the map opens up.
Sounds like Petter is just a submissive who's willing to try to top for his partner even if it's what he normally wouldn't do. Some people are naturally more dominant/ submissive and i like when characters have set personalities that don't always center on the mc.
