Summer was supposed to be boring—until Y/N moves into the house next door to the Sturniolo triplets. While unpacking with her family, they decide to introduce themselves to their new neighbours, and from the moment Chris and Matt see Y/N, neither of them can stop thinking about her. As the families grow close over the holidays, Y/N discovers her bedroom window sits directly across from Chris’, turning late-night conversations, playful teasing, and stolen glances into an everyday routine. What starts as a simple summer next door quickly becomes a messy slow-burn full of laughter, jealousy, unexpected feelings, and one question neither brother wants to answer: what happens when they both fall for the same girl?
