Holy plots! xD I almost missed this because I don't go to my shipper all the time.
So, you've put a lot of thought into this and I love it!
Lia will be a tough one for sure because as a general rule she doesn't much care for anyone. Angie would absolutely get on her last ever lovin nerve with her prim and properness because even though Lia does have manners and knows when to use them, she feels there is a time and place for it and anything beyond that is just sucking up or being a goody two shoes. Would be interesting between them, to say the least, I am game.
Willow is a sweetheart and has more patience than I expected, most of the time. I am fairly certain that she would absolutely overlook Angie's vanity once she gets to know her. Willow always needs more friends so definitely should happen.
Keira is high spirited, generally open and friendly so friends with Angie can absolutely happen. She is very much an outdoorsy girl so getting them together outside for some reason or another could work.
Rowan doesn't go out much so her main friends are her housemates and master. Though she has been known to go out for things during the day, if we can think of a decent reason for Rowan to be out and about during the day we can toss them together and see what happens.
She does need more posts <.<'
Lib would be glad for a new friend that isn't a werewolf, so sure! She is a little bit judgemental so there is that, but she isn't mean-spirited, she really got a mean bone in her body. Maybe a little blunt and accidentally rude from time to time...I am certain they would get along great and eventually become pretty good friends.
Val is pretty open and friendly with most people, as long as they aren't being complete and total jerks. She is suspicious of Fae so instant friendship might not happen but if she is civil and respectful things should go smoothly enough.
I do not have the brain for actual plots at the moment because tired, but I am always up for interaction! <3
