The mountains and wilds are filled with spirits, while the human world is full of affection. At the age when courage matters most, Jin'er saves a wounded red fox named Chi Li with a single act of kindness. Chi Li then enters her life with a simple promise. At first, she thinks he is foolish, while he earnestly tries to learn how to be human, leading to one hilarious mishap after another. Gradually, ordinary tasks such as selling tofu, raising poultry, and working in the mountains turn them into an irreplaceable family. Jin'er protects those around her with clear judgment and kindness, while Chi Li responds to their trust with loyalty and action. Rather than relying on illusory good fortune, they create their own happiness by supporting one another, allowing an extraordinary bond to grow into warm and steadfast companionship.
