Several students of the Poong-pa High School are gathered to be filmed in the school promotional video. While the crew gets ready to film, Min-ho, Beom, and the rest of the kids are busy studying, as an exam is coming up. But Yoon-ho and Yoo- mi, who have no intention to study, decide to kill time together. Meanwhile, Shin Ji gets a call from a musical director for an audition.
