A deer runs, fleeing from a leopard to survive. The leopard chases the deer to fill its belly to survive. Just as the leopard's sharp teeth are about to graze the deer's tail, bang! Now, the leopard runs, escaping from hunters with guns to save its own life. But what about humans? What are we running for?

This picture book explores the ever-shifting dynamics of predator and prey, and the hidden laws of coexistence within these relationships. Is it driven by greed, or the balance of coexistence? What is the "Law of the prairie" today, and which direction should we head in the future? Through simple yet thought-provoking text and powerful illustrations, the book subtly suggests the path we should follow and prompts readers to reflect on the environment.
