The café buzzed with conversation, the aroma of coffee mingling with the scent of pastries. David, sat across from his friend, Mark, laughed at a joke. He felt energized. He had recently finished his novel, a story he'd been working on for years, and it had been accepted for publishing. He felt incredibly proud.

Mark smiled at him. "Lily drew something today," Mark said, leaning forward and pulling out a drawing from his bag.

The drawing depicted a colorful cityscape, with a familiar figure standing on top of a skyscraper. It was Zephyr, the super-hero from his childhood, and the memory of the character was instantly powerful. David grinned at the sight. It was like seeing an old friend. He felt a jolt of renewed confidence, a feeling as buoyant as a balloon.
