"Coffee, please," Mark mumbled to the barista, his voice barely audible above the cafe's bustling energy. He felt out of sync with the world, a muted chord in a loud symphony. An envelope arrived at his door, addressed in an unfamiliar hand. Inside, a book jacket, announcing his biography.

His breath hitched. He wasn't sure who was more stunned: him, or the author. He opened the book with a feeling of dread. It chronicled his life, filled with meticulously researched events, yet missing the essence of his self. The author's words lacked the subtle nuances of his own experiences.

He felt like a hollow shell, his life reduced to a series of bullet points. The author presented him as confident and successful. The image was a cruel mockery. He felt a profound emptiness, a void that seemed impossible to fill. The coffee tasted like ash in his mouth.
