It is recommended to watch season 1 first so that you know more about the story problems in this film. After successfully winning in the competition at the high school level. They face a harsh reality. That their school will still be closed because the previous agreement was only a verbal (unwritten) agreement. So they don't have strong evidence to prevent their schools from closing. In order to prevent this, they enter a national competition against universities and make a written agreement to prevent their school from being closed. Honestly, there are scenes that I don't like, such as camouflage using balloons because they are notvery realistic. However, the way they fight and the atmosphere really feels tense.
