Answer: I’m not too good at making up backstories, but what if she was born in the garden of an orphanage/old ladies house, and her parents left her with enough money so the person taking care of her wouldn’t have to worry about expenses? And then, since bunnies mature faster than normal humans, she ended up being super smart despite her youth, and decided to take the money and run away, choosing to fend for herself instead.
Explanation: I hope this helps, you said help with the beginning of the backstory so I did my best. Hope it’s adequate! It’s late here and I can’t think much lol
i dont really know a lot that would help you with making an oc, but if you're having trouble on the backstory part, then try to put yourself in your ocs shoes. imagine what household/setting she grew up in. also why are her parents unknown? did they abandon her? try to think about her qualities as a person and how she acts now as a 15 year old because of her backstory. if she had a dark past then she most likely will either have something to represent that, or she won't act as friendly/open towards strangers. hope this helped in some sort of way
