Well you see that all depends on the author's decision and what they have in mind. That's something I can't decide
How they act around each other all depends on personality, and there are a bajillion personality types and another bajillion ways how those types act around each other. Just like how you act nice to a person because you like them for their good qualities and how you act not so nice to a person who has what you consider bad qualities.
So that's really all up to you because you're the author, that's part of the fun!
