When starting the drama I thought it might be about high schoolers being notorious and how the main lead will handle them but I never thought it will have so much depth in the plot.
The characters were well thought and everyone's arc was showcased amazingly. The plot is well thought and kept me going for more. Not even a single dull moment. If it's not action it's comedy, if it's not comedy it's thrill, if it's not thrill its emotion. They really kept the pace beautifully. The idea of studying used as a metaphor to do right thing, bring justice and get rid of corruption. The idea of study group is righteous people coming together to beat the sh1t out of corrupted people.
The actors did a spectacular job. Minhyun was the best fit for Gamin. AND oh my Cha Woomin is a brilliant actor. The entire cast did an amazing job. The actor playing Sun Cheol was really a show stopper. The cinematography and direction was perfect fit for the mood the drama was carrying. The way through silliness they brought up really big subjects. Since the mood was little silly and comedic the exaggerated fighting scenes never felt like that. Overall it was a good show that left a lot of impact on me.
