Aaron Hotchner and Y/N have been inseparable for as long as either of them can remember. They grew up in the same city, stayed in the same city, and built their lives around each other without ever needing to name it. They have weekly hangouts, shared routines, and a comfort so natural that neither of them questions why Aaron’s fridge is stocked with Y/N’s favorite snacks or why she knows exactly how he takes his coffee. Whatever they are, it’s easy.
