Study Group : Episode 4

Perasaan Ga Min saat ini dipenuhi dengan rasa antusias karena ia sedang berusaha keras untuk belajar. Namun, usahanya ini tidak pernah membawa Ga Min pada nilai yang bagus, jadi ia harus masuk ke STM Yusung, sekolah yang terkenal sebagai sekolah pelatihan gangster. Tidak seperti Ga Min yang memiliki keinginan tinggi untuk belajar, siswa yang bersekolah di sana tidak suka belajar, dan bahkan memilih untuk tidak belajar. Hal ini membuat Ga Min harus memikirkan cara agar ia bisa tetap belajar dan menjadi lebih baik agar bisa masuk ke Universitas yang bagus. Alih-alih belajar sendiri, Ga Min menemukan metode baru untuk belajar, yaitu dengan membentuk kelompok belajar. Jadi ia mulai mengajak teman-teman di kelasnya untuk bergabung, termasuk Se Hyun (diperankan oleh Lee Jong Hyun ) yang pendiam. Namun, Se Hyun menceritakan masalahnya pada Ga Min.

Meskipun masih murid baru di sekolah itu, Ga Min harus terlibat pertarungan yang tidak terduga dengan Lee Hyeon U (diperankan oleh Park Yoon Ho ), perundung di sekolah. Perkelahian ini kemudian menjadi pusat perhatian semua orang yang ada di sekolah. Di tengah perkelahian itu, seorang pria masuk ke dalam kelas yang sudah sangat berantakan itu, dan ternyata dia adalah seorang inspektur sekolah. Melihat apa yang terjadi di sana, wakil kepala sekolah menjadi sangat murka. Tak sampai di situ saja, ia juga memutuskan untuk mengeluarkan Ga Min.

Someone applied to the study group. Ga Min is excited to meet the applicant, but it turns out that it is Ji U, Hyeon U’s twin sister. Kyu Jin, a member of the student council, picks on Ji U, and Ga Min confronts him. Han Wul tells Hyeon U about Kyu Jin who was blackmailing Ji U. Meanwhile, Ranked 1 among the 1st years comes to see Ga Min.

The study group is finally complete. But the school’s top student, Kim Ho Min bullies Se Hyun, who grew up in the same neighbourhood. He tramples on Se Hyun’s pride and beats him up, calling him a poor loser. Ga Min steps up to help him, but it only makes Se Hyun feel like a real loser. After refusing to go to Ga Min’s house, Se Hyun wanders around and ends up running into Ho Min.

Ga Min breaks the curfew that he promised because of Se Hyun, and his mom tries to transfer him to another school. Han Kyeong and the study group, who can’t give up on Ga Min, persistently chase after Ga Min’s mom and try to persuade her. But that’s when the reserves of the Yeonbaek Gang barge in after finding out about Han Kyeong’s plan for Pi Han Wul.

Ga Min runs into Pi Han Ul’s bodyguard, Kim Sun Cheol, at the hospital where his mother is hospitalized. Sun Cheol was working for Pi Han Ul because he needed to take care of his sick grandfather. In order to pay his grandfather’s hospital bills, Kim Sun Cheol decides to go to prison on the false charge of murder instead of Yeonbaek Gang. Ga Min finds out and steps forward to help Sun Cheol with his friends.

The Study Group sneaks into the Reserves General Meeting and struggles against the Yeonbaek Gang. Pi Han Ul forces Kim Sun Cheol to make a false confession to Detective Na Tae Man. Meanwhile, the fated midterm exam finally begins. The Study Group must improve their grades and climb up at least ten places to hold a disciplinary committee against Pi Han Ul. Will they all succeed?

The Student Council Committee will summon Han Ul, and Han Ul’s past is revealed. Han Ul comes up with a scheme to stop the committee. He makes fake news and puts it online to make it go viral. Because of this, the study group members are falsely accused of a school gang. Han Kyeong must make a choice to protect her students.

The study group members find out about the incident Han Ul was involved in a year ago and why he is so obsessed with the school gang. Since it might put Han Kyeong in danger, the members try to come up with a solution to get through this crisis. Meanwhile, Han Kyeong tries to persuade the Vice Principal to stand with her, but she gets in danger instead.
