The protagonist of this book is a male cat. Since the mother cat had an unexpected pregnancy, these newly born cubs were naturally unnecessary in the mother cat's owner's home. Therefore, as their eyes fully opened, they were given away one after another. After many twists and turns, the cat in this article finally settled in the owner's home that it originally selected. However, as it spent time with the owner, its heart Li's thoughts are becoming more and more firm. Due to its own weak spirituality, its thoughts are extremely absurd among its kind. As a cat, it actually thinks that as long as there is a way, no matter what the cost to itself, it wants to be able to guard its master as a companion for one life, even if it is just forty or fifty years.
As a cat, it can only live five years in this life, and it has to give up the opportunity to be reincarnated as a human after death. Instead, it has to continue to be reincarnated in the animal realm, as a little miscellaneous dog, until the ten-year dog life ends normally, and then it can finally be reborn in the body of a man who was prosperous and successful in his career but died young due to a man-made car accident, thereby realizing his grand wish of accompanying his master as a companion.
