Um.... full of cliches, uninspired characters, I liked the worker guys
The thesis was shoved down our throats by the end, the dialogue sounds like some middle schooler wrote it. I'm Korean so I guess I have a different view than a lot of non korean viewers but it doesn't appeal to me. no impact for me, maybe it's because I'm sick of the conventions of k-drama and the tendency to always appeal to pitying characters and stuff
don't get your hopes up because of the hype. if you like action, social commentary, interesting characters and an engaging plot, watch netflix k-drama "Extracurricular".
