The key scraped in the lock, a sound that brought a shiver up Leo's spine. He pushed the heavy oak door inward, and the scent of lavender and old paper enveloped him. It was a smell that whispered of bedtime stories and summer days. He reached out, his fingers tracing the worn wallpaper in the hallway, a familiar floral pattern that felt both comforting and impossibly distant. He remembered his grandmother's hand resting on his shoulder as she guided him through this very space.

He wandered into the living room, the afternoon sun casting long shadows across the dust-covered furniture. He sank into the armchair, the springs protesting under his weight. A faint ache resonated in his chest as he gazed at the photograph on the mantelpiece, a picture of his grandmother smiling, her eyes twinkling. He picked it up, running a thumb over the glass, and a silent, unbidden tear escaped his eye.
