Undercover in the Hong Kong underworld? You call this an undercover agent?

A fake undercover operative walks on eggshells, hides their identity, compromises their conscience to act like a low-level punk, occasionally gives in to a guilty conscience to do secret good deeds, and treats meetings with their handler like clandestine affairs. A real undercover operative possesses daring boldness and meticulous precision, acts with ruthless ruthlessness, and openly slips intel to the cops to take down their rivals.
