The story starts at Daehan High School. Many students are in trouble because their teachers are afraid of rich parents. Bullying is common, and no one helps the weak students. Then Hwa‑jin comes and stops the bullying, which makes the story exciting. Each case in the show is different. One story shows how bullying hurts students badly. Another story talks about kids being pushed into gang life.
Later, the show tells about cyberbullying on social media and how it can ruin lives, just like physical bullying. Because every case is new, the show never feels boring or repeated. The first episode takes place at Daehan High School and quickly shows the problems in the school. Many students suffer because teachers are afraid of powerful parents.
In the show, Im Han‑rim and Jin Ki‑joo are both very strong characters. Hwa‑jin controls the scene with her big personality, but Han‑rim brings a new kind of power. She is smart, brave, and sometimes even more scary than her coworker.
We also meet Bong Geun‑de, played by P.O. At first, he looks like a funny hero who makes people laugh. But later, we see that P.O is a very good actor. He makes us feel that his character is an important part of the team.
