About the title
So Chi-min, a champion in several martial arts, gets a job as a substitute teacher and dreams of a permanent position. She soon learns that the son of wealthy and influential parents has the whole school living in fear, bullies the students, and holds the teachers in complete contempt. Her colleagues advise her to keep quiet, and after failed attempts to resolve the matter peacefully, the woman herself becomes the target of vicious harassment from the spoiled brat, drunk on his own impunity. Deciding she's had enough, Chi-min fights back against the scoundrel in an unusual way.
