Okay ...Bella was a hunter of supernatural creatures in the past, same as Carlos ^_^
They were a great team (yes ...they were very good friends in the past.), until in a day, she decided to quit this job.Bella wanted to be a normal girl ...
After her parents died, Bella's desire to be normal has emphasized.Even when Carlos tried to stop her, she didn't quit ...
Many years after the collapse of the team, Bella met Kody :).They became girlfriend and boyfriend. :P
(PS:NOBODY knows the secret of Bella and Carlos!!! So I hope that I WILL NOT catch you saying that your characters knows it!!! Oh and ...you DON'T have permission to copy my ideas, thanks! )
