Never In A Million Years

Allyson and Karabo have a thing going on, but non of them will admit it. Good thing is they admitted it to themselves, but will they ever get together, and if so. Will a jealous witch girl be okay? Will they even manage to last with their age difference to consider...
One of them also has a dirty, hidden dark past. One of them? Or maybe both. You find out.
A journey like non other.
Karallyson is their ship name. Unless you have any other ideas.
