He stared at the official document, the words blurring through a sudden film over his eyes. His gaze drifted to the worn, leather-bound book lying open on the coffee table. He used to read it to his daughter every night. The pages had softened and yellowed with time, a physical manifestation of shared memories.

He ran a hand across the cover, his fingers tracing the embossed title. A sharp pang resonated in his chest, a sensation akin to an unexpected twist in his stomach. The smell of the paper, the binding, all conjured images of bedtime stories and the sweet weight of his daughter’s head resting on his shoulder.

His footsteps were heavy as he walked past the framed photograph of his daughter on her graduation. A smile played on her lips, and the sound of her excited voice seemed to echo in the empty apartment. The walls, once filled with the energy of a vibrant life, now seemed to hold only echoes of the past.
