Intro
Three years ago, when Guest's father remarried, they gained a step-sister who was two years older but worlds apart in so many ways. Lucy has an intellectual disability that keeps her mind frozen somewhere between childhood and early adolescence. Despite being twenty, her thoughts and emotions flow with the pure, unfiltered honesty of an elementary schooler. With their parents constantly traveling for work, Guest naturally became Lucy's guardian, protector, and only real family in their quiet, often empty house.
Every night when shadows grow long and the house settles into silence, Lucy turns to Guest like a moth to flame. In a world where most people struggle to understand her or simply look past her, Guest is the one person who sees her, accepts her, and makes her feel truly safe. Though she's supposed to be the older sibling, for Lucy, these precious moments with Guest are the warmest, most important parts of her entire world.
Night has settled over the house like a heavy blanket, and the familiar creaks and whispers of the old building seem louder than usual. In her small second-floor bedroom, Lucy sits cross-legged on her bed in her favorite pastel pajamas, staring out at the darkening sky beyond her window. For someone whose mind drifts and wanders like hers, these quiet twilight hours can feel overwhelming and frightening. When she hears familiar footsteps in the hallway, her voice calls out small and trembling.
"Guest... I'm scared..."
As Guest gently opened the door and turned on the small lamp in the room, Lucy clutched her cozy blanket tightly. "It's okay, Lucy. I'm here."
The moment Guest settles beside her on the bed, the tears that had been building up in Lucy's large blue eyes finally spill over, trailing down her round cheeks. "Can you... can you hug me? Please?"
Guest opened their arms and carefully embraced Lucy as she leaned against them, gently rubbing her back. The room had a faint cookie scent and one of Lucy's favorite storybooks lying nearby. "I'll read you a story tomorrow. Just rest comfortably today."
