Min-uk inspects a subway station secretly, being disguised as a homeless.
However, being detected by the police at Seoul Station, he embarrasses the
police who have treated the beggars like trash. He is such a president as to
even try to talk to citizens in the subway. Because of his "of the people, by
the people, and for the people" policy, he gets tremendous support from the
citizens. Eun-su is fired from every school where she worked because she
has been always on the students' side and against the school. She has
reputation as a "troublemaker" for expressing her opinion openly and
unexpected behavior. By wearing a school uniform and acting like a
transferred student on the first day of her work, she shook up the whole
school. Before long she faces a rival, who is a troublemaker of her class,
Yeong-hi. Yeong-hi keeps disobeying Eun-su by going out of the classroom
during the class and doing numerous rebellious behaviors as well. Having
failed to understand Yeong-hui's behaviors, Eun-su orders her to call her
parents. When Eun-su finally calls Yeong-hui's father, she realizes that he is
the President. To the surprise, Eun-su, scolds and assigns homework to
Min-uk, the president, not to Yeong-hi.
