This guy is really impulsive when undercover, he is doing dumb moves such as getting with Yau Yau and moving in together with her. If they moved in why don't they sleep in the same room? what is the point. Besides keeping laughings coin and telling the story to Yau Yau which in turn blew his undercover. The only reason that he is not dead is beacuase he is being protected by Yau Yau and being a real @ss since he should know that once his cover is blown he should get out instead he is just counting that Sem Jie or Yau Yau don't tell to Hau. This guy is an idiot, may be the only thing good he has done is getting together with Yau Yau since everyone wanted to see that.
