Determined to get it back, she enters into a marriage of convenience with Xie Zhiyan, a powerful business tycoon who can see ghosts, agreeing to become his wife in name only. Disguising herself as an ordinary human, Ruan Yao learns to adapt to life among the wealthy while using her puppet strings to destroy evil spirits and investigate mysterious black mist creatures and the secrets of the five great families.

As bizarre murders plague the Xie family and Ruan Yao's true identity as a puppet is on the verge of being exposed, An Huaisheng, another puppet, makes his appearance, and the truth about a distant past slowly comes to light.
