Eliza bounced on the balls of her feet, her cheeks flushed with the thrill of the upcoming concert. She clutched her ticket, a vibrant piece of paper promising a night of electrifying music. The air crackled with anticipation, a buzz that resonated through her very bones. She spotted him in the crowd. Liam. Even from this distance, she recognized the familiar curve of his smile, the way his hair caught the light.

She practically sprinted towards him, weaving through the throng of people. “Liam! Hey!” she yelled over the rising crescendo of noise.

He turned, his eyes widened slightly. His mouth formed a polite, confused expression. "Sorry, do I... know you?"

The question sliced through the excitement like a dull knife. Eliza’s heart sank, a heavy weight in her chest. All the joy drained, replaced by a hollow ache.
