Twenty-four-year-old Su Wan, a graduate of animal husbandry and veterinary medicine, works hard at a private horse farm on weekdays. After a high fever, she unexpectedly awakened the power and could understand the voices of all animals. With this special ability, she successively saw through the hidden pains and worries of animals, saved critically ill horses, untied pets' knots, and discovered many hidden truths. Since then, she has gotten rid of her low-level job and transformed into an animal psychologist, significantly doubling her income. On the way to fame, she encountered ostracism from her peers, malicious calculations, and doubts from the outside world. However, she always adhered to her original intention, listened carefully to the voices of all living things, and moved forward firmly on the road to healing small animals.
