Then coincidence or fate brings together Eun-byul and goofy-looking high school teacher Jang Yi-san ( Yang Dong-geun) in a somewhat sticky situation. Yoo Jae-gon ( Park Jun-gyu), head of an infamous gangster organization, becomes troubled by the future prospects of his only daughter, Eun-byul ( Park Min-young), who refuses to study. The title is a word play since sam in Korean roughly translates to 'teacher' in slang, thus the international title, I am Your Teacher. Based on the Japanese comic series Kyōkasho ni Nai! (in English, Not in a Textbook! or Very Private Lesson), Yang plays a geeky, straight-arrowed, under-qualified high school teacher who becomes a live-in tutor for the troublemaking daughter of a notorious gangster, in exchange for one million won. It aired on KBS2 from August 6 to October 2, 2007, on Mondays and Tuesdays at 21:55 ( KST) time slot for 16 episodes. I am Sam ( Korean: 아이엠샘 RR: A-i Em Saem) is a 2007 South Korean television series starring Yang Dong-geun, Park Min-young, Park Jun-gyu, Son Tae-young, and T.O.P in his acting debut.
