Malachi Barton has been in Y/N’s life for as long as she can remember. He’s her older brother’s best friend, the boy who’s always at their house, the one who plays guitar while she sings, steals food off her plate, and falls asleep beside her during movie nights like it’s the most normal thing in the world. They’ve always been close — maybe a little too close for just “family friends” — but no one’s ever questioned it. Not Y/N. Not her brother. Not even Malachi. Until one night changes everything. When Y/N goes with Malachi to the Zombies 5 premiere and meets his world of co-stars, something shifts. For the first time, Malachi starts looking at her like she’s not just his best friend’s little sister… and once he notices her, he can’t stop. But with Y/N’s best friend harboring a secret crush on him, emotions rising, and the fear of ruining the family they’ve built after losing so much, Y/N and Malachi are forced to face the one thing they’ve never had to question before: What if they were never just friends at all?
