Victory High School is among the lowest-ranking of Seoul’s 178 high schools. Preparation is underway for an information session for prospective students and parents of the 2013 school year. Ko Namsun has survived high school by keeping a low profile. Even though he has the lowest GPA in junior class 2, he becomes the second-semester president with Oh Jeongho’s deciding vote. In the meantime, Kang Sechan, a star instructor from Gangnam, takes on a special post at Victory High School and shows up at the information session for prospective students and parents.
