Liam stared at the ceiling, the familiar popcorn texture blurring through a film in his eyes. He’d found it, the telltale crease in the spine of his journal, left open on the nightstand. His roommate, Mark, had been unusually quiet this week, avoiding his gaze. The knowledge coiled in Liam’s stomach, a tight knot of unease.

The stale air in the room felt thick, heavy with unspoken accusations. He rubbed his temples, a dull ache throbbing behind his eyes. He considered confronting Mark, but the thought brought with it a weariness he couldn't shake. Instead, he reached for his headphones, cranking the volume until the music was a physical force, blocking out the world.
