This drama was on my watchlist for too long, and when I finally decided to watch it i didn't expect it to be that good. The story was interesting and refreshing. This is unlike any high-school dramas I've seen. Extracurricular also gave me the vibes of "how to buy a friend" and "parasite".
Unlike most dramas, extracurricular had a very dark plot. Its well written, there were no plot holes in this drama. The acting was amazing, Kim dong hee as oh ji soo, the quiet and invisible kid at school but also the villain in his story. Park joo Hyun did a great job as well, her being bae gyu ri, another lunatic. Both of them had similar problems, 2 teenagers surrounded by no one but still wanting to lead a decent life. Once you start this drama, you wouldn't be able to stop.
I have no regrets or complaints about this drama, even though the ending left us with a cliffhanger but I still enjoyed it. I would be even more excited if there was a second season coming.
