Fresh, brilliant and taut, Hwang Min-hyun’s show adds up to a knockout

So what’s it about? Well, a lot. Bespectacled, earnest and fitting the usual stereotype of a TV nerd,  Hwang Min-hyun’s Yoon Ga-min works hard, takes copious notes and always ends up third…from the bottom.  Tutors offer no help, so he decides to transfer to a different school, which turns out to be teeming with chaos and bullies, who call the shots using gruesome methods.  Nevertheless, our hero is determined to form a study group, with the help of a reluctant and soft-spoken classmate, who at first, really wants to just survive this school.
