At 3:14 AM, the sound tore through the silence of the room. It wasn’t the digital, tinny imitation he expected. It was the visceral, mechanical cling-clang of a physical bell striking metal. The sound seemed to vibrate the very floorboards.

The moment the file saved, his phone didn’t just buzz; it felt heavy. He set the tone as his default and went to sleep.
