The sunset painted the sky in vibrant hues of orange and pink, mirroring the electric energy coursing through Leo. He’d just finished an impromptu dance session in his living room, the music still echoing in his ears. Every day had a little extra sparkle to it, an energy that made him feel weightless. A package arrived, a sleek, black box. Inside was a book. The cover depicted a silhouette of a man playing the violin, bathed in a spotlight. "The Virtuoso's Symphony," it announced. His heart leaped. He knew the feeling of the stage, the feeling of the spotlight, with more confidence than ever before. He almost felt like he could fly.
