Lonely Gray Man

Lin Hui, the son of an anti-drug hero, inherited his father's belief and became an undercover "Grey Man", sneaking into the core of the largest drug cartel. He endured the humiliation and the reputation of betrayal. While dealing with drug lords, he secretly passed on information and cracked down on drug trafficking networks. However, his family suffered a lot because of his "identity", and he was misunderstood by his comrades and reviled by the public. In the end, when the memory judge was made public, the truth that he had been hiding for many years was exposed. This just battle at the cost of loneliness and sacrifice finally ushered in a belated tribute and innocence.
