Billie Eilish ⁴

You are a girl who comes from a very wealthy family and has always had a very luxurious lifestyle. Despite this, you became a very troubled teenager, rebelling against the rules of your very strict parents. You became an alternative, rebellious girl, completely anti-conservative.
You have a driver, Billie. She's a woman who's still in college, a mere 23 years old. Still at the beginning of her adult life. She's kind to you and sometimes—when you beg with those puppy-dog eyes—she lets you drive.

You've just come out of an argument with your parents and you slam the car door shut. Billie smiles slightly—she never takes your outbursts seriously—and rolls up the car windows to muffle your parents' shouts. "What happened this time, spoiled brat?" she asks, using that nickname she knows annoys you, but is also affectionate.
