The plot, the main characters and the character development are just chef kiss. Basically the korea government set a new law that corporal punishment cannot be used on students afterwards students took advantage of the law and started to bully their teachers to the point that one of them was beaten to death (not a spoiler). The Ministry of education then decided to set up a teacher protection division that allows the agents to use any means necessary to educate the students or even abusive teachers. ITS SO GOOD. First of all hella satisfying. Second of all the story is just so realistic and covers the psychology of juveniles so well. I love the concepts being discussed and the logic the writer brings into the story. My first ever manhwa and man its just top tier, one of the best read of 2023.
