"Yes, Sir. Sorry, Sir!" Promotional Clip 2

Moses Chan: "Who is knocking on my window?"

Moses Chan: "Don't worry. For now, no one has suspicions about my identity".

Ram Chiang: "Starting from this second, you have officially become an undercover cop".

Moses Chan: "Undercover?!"

Narrator: "Chinese teacher regretfully enters the Avici Hell".

Moses Chan: "Get close to the students, get information, solve the case, and then become a true cop again!"

Moses Chan: "It's nothing...."

Narrator: "Extraordinarily brave cop challenges the underworld".

Ron Ng: "There's reason to believe that you are arranging for dark powers to invade the school".

Ron Ng: "Law Sir is always keeping close to Chiang Hung. Doesn't seem to be simply a teacher".

Narrator: "Sir versus sir. Really don't know what's going on".

Moses Chan: "What?!"

Ron Ng: "I am obviously targeting you!"

Moses Chan: "The underworld has an additional sense of bloodiness again".

Narrator: "'Yes, Sir. Sorry, Sir!' April 18th @ 9:30pm".

Personal Note: He he.... Moses' vocals featured again.... :D

It is evident that this promo clip was inspired by "Infernal Affairs", as they even used the song that was featured in the movie. :P

Anyway, looking forward to Moses and Ron's collaboration! :)
