The original Su Yang was hopelessly in love and gave Zhou Sheng'an her whole heart, but he treated her as nothing more than an ATM. When his first love returned, he abandoned her. Modern-day overworked office worker Su Yang dies suddenly from working overtime and transmigrates into her body, immediately tearing into the scumbag. She awakens the ability to understand animals and adopts Qian Sui, a proud tabby cat. Short on money, she follows the cat's advice and helps the police solve cases for reward money. She then uses her animal-related ability to crack one major case after another and encounters criminal investigator Lu Yanzhi, as the truth about her origins is finally revealed.
