The cafe buzzed with the afternoon rush, but Liam felt an unusual lightness. He spotted her across the room, the woman whoโ€™d been his world as a kid, Sarah. He grinned, that mischievous spark igniting within him. He grabbed a sugar packet, crafting a tiny paper airplane. He'd always been a terrible flier, but the thrill of sending it soaring was irresistible. He launched it, aiming for her table.

It barely made it halfway. She didn't look up. Undeterred, he grabbed another, this time trying a different fold, a sharper angle. "Psst," he called, his voice a low, teasing rumble. "Excuse me, miss? Incoming!"

She finally turned, eyebrows raised, a polite, slightly perplexed expression on her face. He felt that familiar flutter of excitement. "Do you remember the 'great snowball fight of '98'?" he asked, a huge grin spreading across his face.

Her face became blank. "I'm sorry, I don't."
