Watched this series with high expectations but ended up disappointed. It was good when they just focus on how Blacklist solve the case in school but when they start to give the romance between the veggie gang and blacklist I started to feel annoyed. Is it necessary though? The Principal supposed to be the main villain here but they still want to give some unnecessary twist by putting Teacher Jin is a villain you didn't know. The closing was rushed. How did Fah escape from Teacher Jin? How did the teacher asked her to write the letter to framed Traffic? Is The God's Hands already handled? And how did Teacher Jin still teaching when she supposed to turn herself to the police?
