Mark, Timmy and "King" their puppy are best friends. They are always together, playing together and doing things together. They go for walks together, build tree houses together, play together. It was a fun time. But not long after "King" passed away. Mark and Timmy cried a lot. 

The dog "King" in the next life turns into a black cat and has sparkling eyes as if it can talk. And especially that this little cat can remember all about his past life. And so the cat's adventure began.

In this life "King" was born into a rural family. He was helped by a boy named "Robert" to escape from the house. "King" decided to follow Robert to a big city not far from the town they were in. There are a lot of thugs here that make Robert and King quite scared.  They went on and on without food. Robert's body began to wear out. He can't go anymore. King just had to go and steal food. King started stealing at a bakery near them but unfortunately the cat was discovered by the owner. King was dragged across the street by the owner and crippled his leg with a stick. Yet King still brought Robert a piece of bread and a smile. Under the cold winter, snow covered King's feet, making the wound more and more numb. King was still walking around looking for food which made Robert very sad but he couldn't do anything. Then it's time for the little cat to die. Beneath the thick snow, a stream of red blood flowed out. But people don't seem to care about the cat. 

Then the next life will come. King turned into a dog with a long white suit. King knew a dog named Warm. Warm often takes King to find food at a pastry shop. The owner of this shop is very kind. He often gives Warm and King free food. Until one day, Warm told his story to King. Turns out Warm was the shop owner's younger brother in his previous life. In his previous life, because of a conflict with his brother, Warm drove out at high speed and had an unexpected accident. Warm felt very sorry for his behavior and decided to find his brother again. Hearing this, King suddenly remembered Mark and Timmy, he said hello to Warm and then set out to find.

King returns to the place where he died in his previous life. The old houses are no more but now it's just shabby tile roofs. The little cat and the red snow are still there. Next to it was Robert's body. For the first time in his life King's eyes filled with tears. The little dog stayed here for a few days. Carefully bury Robert and the body of the little cat. Then he left in grief. 

After several months of searching, King finally found Mark and Timmy. Mark and Timmy are much bigger than before. But they still miss King. They are finally reunited
