Reborn as a Guard Dog

In his previous life, he was the personal assistant to a corporate chairman, taking the blame, handling drinks, and cleaning up all kinds of shady messes for his boss. In the end, his boss personally framed him, and he spent eight years in prison. After his release, he had nothing. One rainy night, he froze to death beneath a bridge.

Reborn, he became a dog, and not just any dog. He was the golden retriever kept by his former boss.
