Ye Yu, who lost his parents at the age of 5, was taken in by Liu Ying, the gatekeeper of the community. Ye Yu developed the determination to take revenge. He knew from a young age that he had to live well to avenge his parents. Ye Yu's father was killed by a drug dealer. His mother couldn't stand the pressure and wanted to pull Ye Yu to jump off the building. Liu Ying pulled him down. Later, Ye Yu's mother managed to escape and jumped from the 18th floor. Ye Yu was bullied in various ways during school. At the age of 18, he gave up his studies and went to work, but he informed Liu Ying that he had passed away. While concealing his identity and performing a mission, he met Lin Chijun. Lin Chijun thought he was just a gangster who gave him verbal education. Later, they met again and again. Lin Chijun was taken in by Ye Yu's stalker and taught Ye Yu some knowledge about their police station. Feng Shiyu met Ye Yu when he was invited by Lin Chijun to visit the police station, and the three of them became brothers. But Ye Yu always leaves early and comes home late, staying out at night. Every time he came back, he always came back in a panic, which aroused Lin Chi's suspicion. When Su Zhiyu joined, the three of them celebrated the newcomer, but Ye Yu missed the appointment. Every time they got along with each other later, they aroused suspicion in Lin Chijuan's eyes. Once Ye Yu made a mistake, Lin Chijun almost killed him. In another mission, Lin Chijun learned Ye Yu's true identity, but died in the hands of Li Ru while saving him. Ye Yu was forced to inhale drugs before, escaped and became addicted to drugs, and was shot dead by Li Ru's accomplice behind him. The final story only has the development of Feng Shiyu and Su Zhiyu, and there is no follow-up. The story behind why Ye Yu doesn't tell everyone his identity is also a mystery
