It was during his usual late-night internet scroll that he stumbled upon it. Ethan was a creature of habit, and his habit was feeling trapped. He saw the familiar logo of his old university, and with a weary sigh, clicked on the link.

The screen displayed his essay, a testament to his ambition, and the story of how he wanted to make a difference. The story felt like a faded photograph, from a life that never existed. He ran a hand through his hair, a nervous gesture he'd adopted in his twenties, now his constant companion. The room spun around him, a tight, claustrophobic circle, and he felt a cold dread settle in his bones, a feeling he wasn’t sure would ever go away.
