The actual person or the character? But that's the think with senior officers sending out undercovers, they always make them stay longer to fully take down criminal activities
i don't think he's a udnercover. beacuse: Spoiler he had a 1 to 1 talk with gon sai hao, there was no1 around so don't think they were putting on a act why would he even send undercover if he was a bad guy lol
he can still be an undercover placed into the police force by the triads. maybe he want to take over the triad society, that's why he place undercover to take down the big triads. but then that guy doesn't seem charming enough to take on a huge role. since the ending is already this bad. i would've liked it more if they don't show ron became a cop, and show him and laughing fishing on an island on a boat, but don't show laughing's face. hahahaha
