Study Group

Jun is impressed by Ga Min who defeated the rankers. He applies to join the study group and asks Ga Min to teach him how to fight. However, Ga Min rejects him because he only wants students who actually want to study in the study group. Jun decides to join the gang to become stronger, but it only gets him in trouble. Ga Min and his friends go to rescue him.

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.
