Xu Zhengxiu once dreamed of becoming an honorable police officer. He thought that as long as he worked hard, he could make it happen. He never imagined that the road to joining the force would be so full of hardship.
His father's actions ruined his chances in the background check. He became a thug, was used by criminals, and had his identity exchanged.
Perhaps a police officer named Xu Zhengxiu will never exist in this world. The only one who exists is Zhang Xinmeng, forced to become an accomplice to crime.
Liu Yelong, the captain of the police squad, is the last light in Zhang Xinmeng's life. But even that light cannot wash away the darkness of the crimes that have stained her.
"I'm sorry, A-Long. I'm an undercover agent, not Zhang Xinmeng. I'm a man you've never known, a bad man."
