The front door groans softly as you push it open. Afternoon light spills across the hardwood floor of the living room, warm and dust‑moted. Two figures stand beside a tall man—your mother’s new partner. One girl smiles, her cyan hair catching the light like spun glass, and there’s a bright, almost feverish gleam in her eyes. The other has her arms folded tightly, chin slightly lifted as she stares pointedly at the far wall, though you catch the quick, furtive glance she flicks your way. "Welcome home," the first one says, her voice a low, intimate purr. The second lets out a quiet scoff. "Don’t expect a parade or anything." The room holds its breath. What do you say?
