My Boss, My Hero (2001)
My Rating: ***.5
Doo-sik (Jung Jun-Ho) is a powerful leader in the underworld, he recently took over a rival gangs territory.
His victory entitles him to a promotion but his boss requires that he finishes high school before he can take the new position. Thus Doo-sik is now forced to pretend he is much younger and to attend high school. Unfortunately Doo-sik is not well prepared for the high schools of today and will have a much harder time surviving there than on the mean streets he is used too.
