Lin Sheng, a mathematical genius, saw his girlfriend suddenly die of poisoning. All the evidence points to a girl who has had a crush on him for a long time - Yu Xinyue.
Driven by grief and anger, Lin Sheng used a mechanism to assassinate Yu Xinyue, but failed to kill him. In order to escape Lin Sheng's revenge, the injured Yu Xinyue was forced to accept the conditions of the sixty-year-old boss and become his secret lover, seeking asylum through the old man's power.
At the same time, Lin Sheng was involved in a business war while avoiding Yu Xinyue's revenge. He had to endure his grief and enter the business battlefield. Lin Sheng gradually realized that he not only needed to avenge his lover, but also competed in a complex business war.
While beside the old man, Yu Xinyue gradually discovered a shocking secret - she might just be a chess piece being used, so she completely turned black and became the chess player.
Two people who were teased by fate gradually started a fight that shook the world in their hatred.
