The world felt bright. Sunlight bounced off the freshly fallen snow, causing Maya's eyes to crinkle as she skipped down the street. The thought of the evening ahead had kept her occupied all day, and now she was almost there. It was all she had been dreaming about for weeks.

She pulled out her phone, anticipation making her fingers tremble. She'd been checking for updates all day, and now, finally, the moment was at hand. She refreshed the group chat. A new message. From Liam. Maya’s excitement curdled.

"Okay, so, total disaster. The place fell through. Party is off."

The world seemed to dim slightly. The vibrant colors of the snow seemed duller. Maya found herself staring blankly at the screen.
