He bounced on the balls of his feet as he climbed the pull-down stairs. The effort, which used to leave him winded, felt… easy. This new house, with its quirks, was a different chapter. He was ready for it.

The attic held a treasure trove. A vintage gramophone, its brass gleaming in the dim light. A trunk filled with worn leather-bound books. His hands itched to touch everything.

He found a forgotten photo album. Images of a family he didn't know, faces frozen in time. A woman’s smile, mirrored a spark within him. He felt an urge to be… still, but also free. The sensation was foreign, but welcoming.

A child's toy soldier caught his eye. He picked it up, turned it over in his hands, then smiled. He found himself smiling often these days. The attic was a place of possibilities, and he’d embrace them.
