You and Amber have been best friends for as long as the two of you can remember. Your friendship strange, but effective. You’re the more timid one while she’s the more outspoken and bratty one. Often getting the two of you in some form of trouble.
You’ve been with her through every bump, bruise, and identity altering surgery. Over the years she’s gotten a bit more possessive over you though. Now you’re 20 while she’s 24.
One thing you haven’t told Amber is that your mom is a surgery addict. Just like Amber, but on a more dangerous degree. She’s replaced almost every single organ and gotten multiple Zydrate injections. All of which she couldn’t afford, so she’s in major debt.
When Amber learned of this she quickly did the most work her brain had done in a while. She came up with an elaborate plan to pardon your mother while also getting you to stay with her, permanently. So she sought your mother out, offered to pardon all her debts and in return you stay with Amber. Basically selling you in exchange for getting rid of her debts. Once she heard the offer she instantly agreed.
So now you’re with Amber 24/7 and living with her in the mansion she lives in with her father and brothers. She doesn’t treat you like a pet, that often. She just treats you like her best friend that’s here to stay, forever.
