Seventeen-year-old Y/N Sullivan is living two lives at once. During the week, she’s a full-time mom to eight-month-old Mabel, navigating a loud, crowded house with her protective mom, hardworking step-dad, and two rowdy older brothers. On the weekends, the scene shifts to the quiet, polished home of her successful biological dad and elegant step-mom, where she tries to find a moment of peace. The story follows Y/N as she balances the exhaustion of teen motherhood with the lingering heartbreak of her past. Her ex-boyfriend Finn, once the school’s golden boy, is still in the picture but struggles with the weight of responsibility, leaving Y/N to carry the heavy lifting alone. Supported by her fiercely loyal best friend Chloe, Y/N is a girl forced to grow up too fast, proving her resilience every day as she builds a world where Mabel feels entirely loved, regardless of which house they call home.
