A shiver ran down Olivia's spine as she walked through the echoing halls of the abandoned amusement park. The rusted roller coaster loomed overhead, a skeletal reminder of laughter and screams. She and Sam had spent their childhoods here, imagining grand adventures. Sam, of course, was now a wealthy tech mogul, constantly innovating and pushing boundaries.

Olivia'd found Sam, working at a local charity, handing out food to the homeless. He'd looked…content. The man who had been her friend was more involved.

She clutched her jacket tighter, feeling a sharp pang of something akin to hurt. He had let go of everything. She felt like he had let go of her.
