Molly, who traveled through the world of beasts, was gently adopted by the snake king Mo Benhai and entered into a marriage contract. He made an exception to light a fire, search for fabrics, and made a solemn promise for her. However, the appearance of human female Lin Xueer broke the peace-the snake king gradually became partial and ignored Molly, while Lin Xueer intervened wantonly in their lives. Molly, who was starving for food but was captured, unexpectedly gained the empathy of other female snakes and the closeness of the puppy in the complicated emotional entanglement of the snake clan. A journey of guardianship in the beast world about sticking to the truth and regaining exclusive tenderness began.
