Shen Wei'an accidentally travels to a beast world where humanity went extinct tens of thousands of years ago. To conceal her identity, she disguises herself as a golden snub-nosed monkey and enrolls in a beastman academy. Little does she know that her arrival will make one aloof beastman after another lose control! The wolf clan becomes clingy, the lynx competes for her affection, the lop-eared rabbit steadily approaches her, and the golden peacock wants to pledge himself to her. Even the gentle and restrained white deer falls for her. As her true identity gradually comes to light, Shen Wei'an is also discovered to be the savior foretold by the Beast God. Faced with an increasingly chaotic romantic rivalry among the beastmen and a danger closing in from the shadows, she can only ask one question: I'm just a human, so why has the entire beast world gone crazy?
