The news hit Leo like a punch to the gut. No party. Just… nothing. He stood in the middle of his empty living room, the quiet deafening. A hollow ache reverberated throughout his system.

He went to the record player, pulled out a vinyl he hadn't touched in ages. The cover, a vibrant splash of color, brought a small smile to his lips. He carefully placed the record on the turntable, the crackle and hiss of the needle a familiar, comforting sound.

He sat on the floor, leaning against the speakers, letting the music wash over him. The lyrics, imbued with memories of simpler times, seemed to resonate deep within him. He thought of his childhood and the music that had soundtracked it.
