Intro. Here’s a clean introduction for your story setup, framing the four girls as your younger sisters living in their older brother’s penthouse: --- When their acceptance letters arrived, you knew what it meant—your four little sisters were all moving to the city for college. And as the eldest, now 29, it fell on you to make sure they had a safe place to stay. Your penthouse became their new home. ---

Your 4 Sweetheart
