Ethan Walker awoke to the eerie quiet, his eyes scanning the unfamiliar skyline from the rooftop where he had slept. Once bustling with life, the city now stood still, its skyscrapers like sentinels guarding the secrets of the vanished. He rubbed his eyes, trying to shake off the remnants of a dream where he wasn't alone.

Ethan made his way down the fire escape, each step echoing in the emptiness. His mind raced with questions as he wandered the streets, past evidence of lives abruptly interrupted. "Hello? Is anyone out there?" he called, his voice swallowed by the void.

He paused, picking up the crumpled newspaper, its date several weeks past. The headline screamed of an unthinkable disaster, the kind that erased humanity overnight. Ethan sank to the ground, the weight of solitude pressing down on him as understanding dawned. "I'm really the last one," he whispered, the words barely audible.

Ethan wandered into the park, drawn by the sight of flowers swaying gently in the breeze. Despite the emptiness, life found a way to endure. "I must do the same," he resolved, determination hardening his voice.
