Si-eun, a junior in a vocational high school, lives with disappointments while feeling inadequate in her teenage life. She reveals her hopes of attending college in Seoul during a career counseling session, but she is advised to reconsider. Kyu-ho is the head of the dance sport club at her school. When he encounters a possible closure for the club, he begins a search for more members to enter the upcoming competition.

Si-eun entices her friends to join the dance sport club while imagining a successful future by becoming famous with her newly found interest. On the day of the audition, they are all accepted into the club out of the club's necessity. During the initial introduction among the new members, another person is found hiding inside one of the club’s cabinets.

Seung-chan is discovered hiding inside a locker during the introductory session for the newcomers. He tries his best to explain his true motive with the dance moves he learned by secretly watching the club practice. The dance lesson continues for the members, concentrating on the upcoming competition. Being assigned to Hye-jin as a partner, Si-eun reluctantly accepts the challenge amidst her frustration.

The girls continue preparing for the competition, even by taking time out to practice individually. Si-eun tries to apply the advice from Kyu-ho during her practice. The club is excited about the first successful team routine involving all members. Si-eun's perspective toward Hye-jin improves when she sees her efforts in cooperating with the team. On the day before the competition, Hye-jin suffers a motorcycle accident resulting in a broken leg. The members are dismayed by the circumstance, unsure of how to proceed.

The dance sport club ends up being the laughing stock of the competition. Si-eun and the other members are appalled to see their poor performance spread across the Internet. The school decides to announce the closure of the club due to its poor performance in recent years. Despite the circumstances, the girls begin to seek ways to revive the club once again.

Executives from Daeung arrive at the girls’ school expressing the desire to become a new sponsor for the dance sport club. The foundation also offers a college scholarship for Si-eun. With the new hope the club has found, it begins to prepare again for another competition.

Seung-chan decides to share his admiration for Si-eun with her privately, but she tells him that she can’t accept it. Kyu-ho forfeits the sponsorship from Daeung and decides to spend his own savings to run the club. He takes the members to the professional competitions, reminding them that future preparation will be held at a higher level.

The club members happen to come across Si-eun’s text messages on her laptop. They realize that she has used them to build a good background for her college admission. The members begin to distrust and neglect her as a result. The club identifies a need for someone to fill the male role in their routine and begins searching for the right individual.

Seung-chan’s secret endeavor of participating in the dance sport club is uncovered by Dong-suk. He is questioned about his hidden practices, but responds adamantly with his will to continue his mother’s lessons. Seung-chan then proceeds to ask Kyu-ho for permission to be on stage with Si-eun for the duet performance. The two complete the performance with praises from the audience.

Si-eun visits Dong-suk to inquire about his past relationship with her late dad. Dong-suk admits his acquaintance with him. Si-eun then mentions how she is indifferent towards others’ opinions about her family, but wishes Seung-chan to be kept from being hurt by it. The dance sport club is ecstatic to learn that they have been qualified for the competition preliminaries.

Kyu-ho decides that it is time for a team retreat before the upcoming competition. At the retreat, he shares his experience with past members who had resigned for dishonest reasons. He also shares that he started the club to retain the students who were neglected by the school for their grades. The members also have an opportunity to discuss the obstacles they must face to continue to participate in the club.

Mi-young pays a visit to Si-eun’s school for parental counseling regarding Si-eun’s college options. Dong-hee suggests possible opportunities for Si-eun, but Mi-young rejects the idea for what has been observed from Si-ra. The club members repent of not being fully prepared only two weeks before the competition, determined to dedicate extra time to master the new choreography.

The club members learn of Kyu-ho’s imminent transfer due to the recent set of events. They also become aware of the only way to prevent it, which is by winning a national competition. Si-eun receives a letter back from the scenario contest for winning the Grand Prize. Mi-young is unable to believe the result, and she worries about providing the cost for Si-eun’s college admission.

Seung-chan is excited about his college outlook and shares that he is also preparing for technical majors to Si-eun. She criticizes him for hiding this from her and asks if he really is committed to his dream. Seung-chan is unable to understand her irritation and assumes that it's related to her financial situation. He offers to help, but she responds with her wishes to no longer continue the relationship.

The senior members of the club are at a job fair in ready for their graduation. They are pondering various possibilities while selecting where to apply. Si-eun has decided to withdraw from submitting her application to universities and to also participate in job interviews. Dong-hee suggests she continue her education, but she declines it by saying she does not regret her decision to give up on her dream.

Si-eun attends the university admission interviews and begins to contemplate the reason for choosing the film major. The probability of entrance for her seems unfavorable, being among the overwhelming applicants. The club members settle with their plans on post-graduation life and promise to reassemble even after graduation.
