Korea Secret Agency (2006)

Description:

Choi Kang (Eric Mun), a freeloader at home, has a hard time finding a job after being expelled from high school for fighting. He is admired by the gangs for his fighting ability, but his younger brother, working in the prestigious LK Corp., looks down on him. Then a little luck, and a bit of fortune lands him a meeting with the President and a job at the KSA (Korean Secret Agency)... and perhaps a girl or two are coming his way as well.
