The male protagonist Huang Yi, originally an orphan from an orphanage, was later adopted and raised by Ding Zhen, the chairman of Zhentian Group, and became the president of the East District, one of the four major divisions of Zhentian Group. Three years ago, Ding Zhen's only daughter, Ding Nian, mysteriously disappeared. Huang Yi accidentally discovered in Pengnan Town that a delivery worker, Lu Yao, looked exactly like Ding Nian, and therefore asked her to impersonate Ding Nian. When Huang Yi brought the fake Ding Nian, Lu Yao, back to Zhentian Group, people in the group began to die mysteriously one after another. Huang Yi and Lu Yao were forced to be embroiled in a life-and-death maze, and the two of them also unknowingly went from bickering enemies to gradually falling in love with each other through their time spent together.
