Synopsis
In 2009, Kang Bok-soo is enrolled as a junior at Seolsong High, a prestigious private high school known for its discriminatory practice of segregating students based on their grades and social status. Bok-soo is a routine troublemaker who scores poorly in tests, but he is also popular for being a bully hunter. He dates the school's smartest student, Son Soo-jung, who doesn't reciprocate entirely, and is also best friends with Oh Se-ho, the awkward son of the school's abusive board chairwoman, Lim Se-gyeong. Soo-jung has long been hiding the fact that she is poor, but her background is suddenly outed to the school a day after she discloses it to Bok-soo, causing her to believe that he cares for her out of simple pity. When she heads to the roof to mourn, she hears Bok-soo and Se-ho having an argument, ending with the latter falling. Se-ho survives the incident and testifies that Bok-soo pushed him. Soo-jung, still heartbroken by Bok-soo's apparent betrayal, testifies against him as well as revenge, leading to his expulsion from Seolsong. Nine years later, Bok-soo is working at Your Request, a general service company. Soo-jung is struggling to receive a promotion as a permanent teacher at Seolsong and was unwittingly scammed to pay a hefty sum of money to become one. She is currently counseling Oh Young-min, a troubled student of Ivy, the school's highest-ranked class. She talks down Young-min when he attempts to commit suicide by jumping into the Han River, only to end up falling down with him. Bok-soo, who happens to be standing nearby, saves her. His heroic action forces Se-ho, recently promoted to become Seolsong's board chairman, to re-admit Bok-soo into the school and appease public opinion. Bok-soo enters Wildflower, the school's lowest-ranked class. Se-ho pulls some strings to promote Soo-jung as permanent teacher and gives her the job to mentor Wildflower. Bok-soo devises a plan to take revenge against Seolsong, and Se-ho in particular, for the lies that caused his expulsion. Though initially chilly, Bok-soo rekindles his relationship with Soo-jung when they learn that their grudge was driven by a series of misunderstandings and her hate: Se-ho was the one who gossiped Soo-jung's background and framed Bok-soo into playing the part of his rooftop fall, which was actually a suicide attempt. Se-ho has long been in love with Soo-jung and framed Bok-soo precisely so they would split. When Soo-jung confronts him about this, he openly admits his actions and warns her that, for rejecting him, he would make her and Bok-soo's lives miserable. Aided by his friends, Bok-soo slowly dismantles the corrupt atmosphere of Seolsong. In the process, they have to face the school's entire upper management, all of whom want to preserve the status quo. Upon collecting enough evidences, Bok-soo uploads a video containing documents that implicate Seolsong's corruption. The ensuing scrutiny convinces Se-gyeong to depose her son and engineer a scapegoat so the school's reputation could be protected. Se-ho, having had a change of heart and sick of being mistreated by his mother, forms an alliance with Bok-soo to further scrutinize Seolsong and bring them to court. Bok-soo publicizes Se-gyeong's plan to turn Seolsong into a corporation, and Soo-jung further testifies against her at the cost of her job. Se-ho, meanwhile, admits the truth about his suicide attempt. Not willing to surrender, Se-gyeong blackmails Se-ho into becoming a scapegoat and plans to close Seolsong. Bok-soo, Soo-jung, their friends, and the teachers band together to prevent her from entering the school long enough until the police arrive to arrest her, having been tipped by Se-ho regarding his mother's crimes. In the aftermath of Se-gyeong's arrest, Seolsong becomes a public school. Se-ho moves to theCast

* Yoo Seung-ho as Kang Bok-soo :A rowdy and selfless young man who got expelled from Seolsong High for a crime he was falsely accused of. Nine years later, he is invited to attend the school again, despite being 25 years old, and plans to take revenge by reforming the school establishment. His lack of a high school diploma closes the door to many job opportunities for him, making him rather bitter, but Bok-soo possesses a strong sense of justice and is eager to fix other people's problems. Bok-Soo hates Soo-jung and Se-ho but never acts on it fully. * Jo Bo-ah as Son Soo-jung :Nine years ago, Soo-jung was Seolsong's smartest student and Bok-soo's girlfriend. However, their relationship fell apart when she thought he betrayed her by exposing her biggest secret: poverty. Soo-jung responded in kind and told the investigators of Se-ho's accident what she heard, in hate towards Bok-Soo, sealing the decision to expel Bok-soo from Seolsong. Since then, Soo-jung has been living in regret, but the memory of the betrayal prevents her from reconciling with Bok-soo until years later. Though she appears wholesome, Soo-jung is headstrong and uses crude language, which Bok-soo brands "two-faced". Soo-jung's dream is to become a teacher, something that keeps her motivated throughout her rough life. * Kwak Dong-yeon as Oh Se-ho :When he first enrolled, Se-ho was the awkward son of Seolsong's ruthless chairwoman and led an unhappy life. His mother is shamelessly abusive and deadbeat, something that traumatized him for life. He is jealous of Bok-soo for having a loving family and dating the girl Se-ho has a crush on. He eventually attempted suicide, but survived and framed Bok-soo at his mother's urging. Nine years later, Se-ho takes over as Seolsong's chairman.Supporting
