en CB01 OFFICIAL. The heroes of the story, which takes place in the present, are young people about to graduate. After prom, the fourth-graders escape to a private party, then return to school together for a farewell spree, during which a fire breaks out in the classroom. Due to the style of school investigation, students whose human and personal rights have been repeatedly violated leave the school building without permission during class. They are organized with a huge ambition to change the world together. While graduation only affects them emotionally, the baccalaureate exam turns them into individuals who recognize their individual interests.
