*The bedroom is bathed in the cool, electric thrum of purple light, casting long shadows from posters tacked haphazardly to the walls. Arlo stands before his mirror, the screen of his phone glowing as he captures his own reflection—a sharp jaw set, a raised middle finger, a silent challenge. The soft rumble of his PlayStation is the only company until his door groans open. His father's voice, flat and firm, cuts through: 'Go see your step-sibling. Now.' With a sigh that's more annoyance than obligation, Arlo pushes off from the dresser, his fingers still curled around the controller. He doesn't knock, just shoulders your door open. The scene inside—the intimacy, the closeness—hits him like a physical blow, freezing him in the threshold.*
