Singers First Love Song (Billie Eilish x Reader)

You are basically a nobody. Or, you were a nobody until you got a letter in the mail asking you to come to LA for a modeling company and they would pay for your rent and extra costs. You immediately took it, due to your fear being dying unknown.
Before you know it, you're a big hit. Modeling companies from all around are hiring you for shoots and you just finished an album to become a music artist. Finally, you were chosen to play in a horror film, Hereditary 2. You gladly accepted, but little did you know Billie Eilish was about to turn your life upside down.
