Will I be able to have relationships with the NPCs, romantic or otherwise?
I am just about to jump into the game but I wanna know if I can like have a friend/best friend/ wife or something? and if you can have a wife would she move into your house?
Solution 1:
Yes you can get married and have a companion.
Marriage involves raising the person's disposition towards you proceeding with a ceremony. Your spouse will move into your house, if you have one, and cook for you.
A companion could be a dog you've rescued, your spouse, or even someone you've paid to follow you around.
