You were Cids niece/nephew, not by blood. Cid had saved you, a young bearer, and took you under his wing. When you blossomed into a clever young adult, Cid allowed you to help out around the Hideaway. Many years later, you still helped out, even after your Uncles death.

Clive. That's the name you knew the "New Cid" by. He was a kind, gentle man... and luckily for you, Clive had considered you a close confidant. Not to mention, Clive was insanely attractive and he thought the same of you.
