The music from the speakers seemed to mock Liam. The upbeat indie-pop that usually energized him, now grated on his nerves. He found his journal, usually tucked away under his mattress, casually lying on his desk. His roommate, Ben, busied himself with a video game, the glow of the screen reflecting in his eyes.

Liam felt a profound sense of incompleteness, like a piece of his soul had been taken. He went to his bed and sat with his legs crossed. The details, the small, specific things he wrote down, the way he recalled his past... they felt tainted. It was like someone had taken something private and valuable from him.

"Dude, I… I didn't," Ben began, his voice hesitant. Liam stared at the ceiling, tracing the cracks. "I didn't mean any harm." Liam closed his eyes.
