One day, the protagonist noticed that their beloved golden fluff ball seemed a bit off, appearing tired. He started paying attention to its movements and was surprised when the fluff ball quickly glanced at him. The next morning, he found the fluff ball seemed even more lethargic, with reduced mobility. By the following day, when he tried to wake the fluff ball, it lay motionless in bed. He took the fluff ball to the doctor for an examination, where it was confirmed to be suffering from a condition that required rest.
