I already have the relationship at level 3 with all of them, but it's missing the final interactions, which are the encounters in the bath.
Oh, there are many more. I'll assume because you asked you (hopefully) don't mind me spoiling the locations. Aside from what you know, there is the Church, Lake, Bakery, and the Other Village. You can unlock these by getting closer with Uriah, Odachi, and Kamau, respectively. I don't remember exactly how to get to the other village, but its probably through Terrance. That's it for now. It's a bit of light grinding though.
