Zeng Xiaoyu is a timid and gentle girl. Her biggest dream is to be with her senior Lu Zixuan, whom she has had a crush on for five years. When Lu Zixuan finally confessed to her, she was ecstatic. However, she soon discovered that she was just Bai Yueguang and Su Wanqing's stand-in - a "tool man" who could take care of spiritual pets. After Su Wanqing went abroad, Lu Zixuan's spiritual pet "Xue Tuan" had no one to take care of him, so he chose Zeng Xiaoyu.
The most cruel thing is that Lu Zixuan set up a spiritual pet contract with Xuetuan: once Zeng Xiaoyu stops taking care of her, the spiritual pet will attack her. Zeng Xiaoyu was trapped in this twisted relationship, watching Lu Zixuan call other people's names to her every day, and had to endure Xue Tuan's troubles. But she didn't know that the sleeping power in her body was awakening - she was the real owner chosen by the ancient spiritual pet.
