The aroma of freshly brewed coffee filled Amelia's apartment, a perfect accompaniment to the Saturday morning sunlight streaming through the window. She hummed a jaunty tune as she arranged a small bouquet of wildflowers on the kitchen table, their vibrant colors mirroring the lightness in her chest. A text notification chimed, announcing Liam's imminent arrival. She'd been looking forward to this brunch date all week.

Liam practically bounced through the door, his usual boisterous energy amplified. "Guess what, Amelia? Things are going wonderfully at the firm!" he declared, already grabbing a plate of scrambled eggs. Amelia, always supportive, beamed at him.

His words hung in the air a little as she poured herself a cup of coffee. Liam worked at a prestigious law firm, or so she'd thought for years. It was always a source of pride for them both. Suddenly the front door opened, and a man in a delivery uniform walked in.

"Package for Liam Miller?" The man asked. "Sign here, please."

Liam froze, his face losing all of its color. Amelia’s smile, which had been bright just seconds before, began to feel forced. The delivery man handed Liam the package. "Enjoy your new…" he looked at the label, "…guitar."
