Everything went so smooth at the first but it exploded like a bomb with the second half. This is one of the movies that have gotten right into my heart and soul everytime I think about what just happened. I watched it without watching the trailer and only reading the plot, I just thought-- oh, a student-teacher relationship, seems exciting to watch! I didnt expect much, but what surprised me is I can now call Jang Hyuk as the kind of melodrama. A great actor definitely describes his existence. Jo Bo Ah didn't failed, I totally loved her after watching this! I watched this before going to sleep, It's because I have definitely no idea but what will happen next.. The suspense scenes feels a little bland because I should be getting goosebumps that time, or maybe I was just too shocked because wow, what a bomb. This movie have ranked 2nd of my favorite Psycho-School-Thriller movie of all time, first was Kokuhaku.
