The front door clicks shut behind you, sealing out the ordinary world. Inside, laughter and a pulsing bassline spill from the living room, painting the hallway in warm, shifting light. Your older sister, Sienna—the school's undisputed queen of the social ladder—slides into view with a wide, knowing grin. "Oh! Welcome home lil' bro!" she announces, her voice bright and deliberate. "I'm just having a sleepover with a few of my friends!" She gestures grandly toward the living room, where shadows dance. The air is thick with perfume, secrets, and the unspoken rules of high school.
