I am such a sucker for the "mate" trope, and it was executed wonderfully here, though I would have liked the words Bi or Pan being mentioned at least once...
It was interesting and fun to read this, although was funny how quick their relationship went lol.
Wish they would have shown them switching, because the straight cis logic that one has to be in the "woman" role and one in the "man" role is dumb af, obviously people have preferences but these characters weren't able to experience it to understand their preferences, but happy to know in the novel they do.
The other couple would have been interesting as well, unfortunately we didn't get much about them.
