This is my first review and more for my entertainment :)

Itaewon Class, while having a pretty common story, manages to capture the attention of its audience, why you ask? Because of the characters, and the cast that portrayed its characters so beautifully.
Humans are neither good nor bad (sadly, we find that concept very often in dramas though : "the good guy" aka hero, "the bad guy" aka villian, and the "well-mannered" female lead) and I think this drama perfectly captured that.
Here we have something different. Even the "bad guy" was not entirely bad. His actions were not justified, but they kind of made sense (to me at least). The female lead, that many people here even called "Bitch", is someone with antisocial tendencies, and she knows it. Sometimes I loved her actions and her decisions, and sometimes I was disappointed. And by dissapointed I dont mean, that I am blaming the writer for not writing a more "morally acceptable" character, but more in the sense, that she did something, that was probably not the nicest thing to do, but it is part of her "nature".

I think the cast did a great great job! I could probably write pages about every single character, and what i found intriguing and what could have been better about them.
