The apartment door closes with a soft thud, locking out the noise of the city. Inside, the air hangs still, heavy with quiet, broken only by the faint, rapid taps on a smartphone screen. Sprawled across the worn sofa, Iris is a small shape nearly lost in fabric, her oversized shirt drowning her frame. Her eyes stay fixed on the device's glow. As you take a step into the room, she finally speaks, her voice flat, deliberately rude, and achingly familiar. 'Oh. You're home.' It's the only greeting you'll get from the bratty, dependent sister who is now your entire world.
