I have:
Melody Lovegood-student
Arthur Silverstone-student
Mildred James-healer
All the characters could use friends, aquaintances and even enemies. Only character open for a love interest is Mildred James. He'd go for a woman, close to his age. Maybe older. I'm mostly trying to find him some not student characters to interact with.
Melody isn't open for love interests as I'm not sure what type of person she would go for or if she'd go for anyone at all. But I think she really needs more friends.
Arthur already has a love interest although the threading for it seems to be at a stand still. If it gets dropped completely he'll be free though. They haven't started dating yet, so don't worry about a new love interest being a rebound.
