A unique drama about school violence. Follows the story of an introvert named Si-eun. I loved his acting I believe it was played to a tee. I also really enjoyed the performances by Soo-ho, Bum- seok, and Seok-dae. I found the rest of the cast pretty mediocre. The storyline was interesting in the first half but was slowly losing me in the second half. My favourite fight scene came from the second episode. Action was engaging and suspenseful. This series was very easy to binge through given that each episode is between 35-40 minutes. Overall a good show, i'm glad I gave it a shot!
