I don't know why IMDB gave only 6.8 to this movie. This was a masterpiece from korea...
only one mistake done with the movie is tha handcuff which locked the killer in thunder Arrester🤔 How it got released from teachers hand!
You can do everything fine and how can you do such a silly mistake 😏
it spoiled the whole movie. 😒
Except that the movie is a great one to watch ❤️
