Hi Strange. I'd be interested I'm threading
Jacob with Lucia. He pretty recently found out about his demonic nature. Very conflicted about it, likes the powers but the demon part scares him. His father Mephistopheles was a selfish monster who abandoned him before he was even born, so now Jacob is scared he's going to end up like that.
I like the idea of them becoming good friends, with her finding out he's a demon later on. Because while he doesn't really actively hide his demonic nature, he doesn't bring it up all the time. She might see his wings occasionally, but that's not a demon only thing.
Could be a good way to grow both characters, and it could be interesting to see where it goes.
