A story about a cat who has memories of a previous life when she was a human woman. While working as a bookstore clerk, she had an accident on her way to work, and before she knew it, she had turned into a cat. After she became a cat, she enjoyed her days as a cat, but when she visited a bookstore run by a man alone, she realized that he was a human against himself.
