The old record player spun a scratchy rendition of a song his mother used to love. The music filled the small apartment, a familiar melody that brought tears to Leo's eyes. He sat surrounded by boxes, packing his belongings for a move. The news, delivered in a letter, of a half-sister, had struck like a blow.

He picked up a photograph of his parents, taken when they were young, their faces radiating a joy that now felt bittersweet. He remembered the feeling of being held, of being safe. The music took him back to the past.

The apartment, once a sanctuary, now felt like a prison. He felt a sudden, urgent need to understand the past, to unearth the hidden narratives that shaped his life. He wanted to go home again.
