The afternoon sun cast long shadows across the living room floor. James, feeling an irrepressible need to move, was pacing back and forth, sketching elaborate dog houses on a notepad. His pulse quickened at the thought of a loyal companion by his side. It was a prospect that filled him with such a deep sense of contentment, a feeling that had him bouncing around like a kid. He knew Chloe, his roommate, would probably whine.

“Chloe!” he called, his voice laced with a cheerful anticipation. "Come see this! I have an idea!" He couldn't wait to share his plan. He already envisioned the walks in the park, the playful games, the unwavering affection.
