For Goong-dahl, nothing has gone right his whole life. In an attempt to discard his ‘losing streak,’ he signs up for and fully immerses himself in a year-long psychological therapy program. Exiting the clinic with high hopes for the future, Goong-dahl makes a fresh start in the high school battlefields. Goong-dahl manages to spot some losers who were bullying the school’s most gorgeous student, Mina. But alas, due to a lack of information about the school’s notorious thug Jae-koo, Goong-dahl mistakes Jae-koo as his prey. Naturally the tables are turned and Goong-dahl is challenged to a rooftop fight after school.
