So I have quite a few choices for you to choose from! Feel free to fit them in your little plot where ever you like :-)

Tetradore - He's a were, alpha of a pack and kinda owns the whole west side. He's kinda hired Sorcha...or something >.> He's pretty apathetic and quiet. If he's around Sorcha a lot, I would think maybe him meeting Tet would be entirely normal!

Chizue - I haven't really played her in a while but I've thought about bringing her back. She's a vampire. Really quiet and shy. I haven't done anything with her so she's kinda open to anything. She could be a love interest if you'd like too. She's the kind of girl who could totally do the one sided crush too.

Alexander (the great) - He's a dark hunter. Kinda jerkish but he doesn't really actively hunt. He's so old that he only really does stuff when it suites him.

Serafina - She's a witch. She's super spicy and kinda a daredevil. Unfortunately she's not up for love interests but she's a loyal friend if you can befriend her!

Just let me know if any suite you and if not I totally understand too :-)
