I'm still shaking off goosebumps after finishing the movie. I thought I knew what I was getting into and I prepared myself for it but I didn't know I'd still be this jarred. I'm not really sure yet whether I like this movie or not, but what I cannot deny is that it is a very strong and solid film. The story is not a very complicated one. You have an obsessive school girl who's crazy about her teacher and thinks what they have is love. The teacher wavers slightly and pays the price for it with his family at stake. A simple setting but what sets this movie apart are the layers of complexities in each character's personality. More so than the obsession, the film makes you see these characters as individuals whose stories you are watching. A really well directed and written piece. The actors did a splendid job. Jang Hyuk and Jo Bo Ah were completely engrossed in their roles. I really need to mention that these people have a huge age gap in real life and to portray such a tender and hard-to-digest topic with such realism is commendable. There were times when I was too repulsed to watch the scenes but couldn't take my eyes off of the screen because the actors were doing such a brilliant job. Worth the watch for the actors' work if not anything else. It is definitely not something just anybody can see. You need the appetite for this sort of movie. When they say there's lust, betrayal, obsession and revenge, they mean it. There's no sugarcoating anything here. Just raw emotions. In fact, I don't think I'd be able to watch this movie again even if I wanted to. Everyone gave such a powerful performance, It's going to stay in my head for a long time. I might not have enjoyed this movie in the true sense of enjoying a movie, but I sure respect and admire the work. It's a really good movie. Not made for everyone though. It's also rated R because of explicit scenes that are shown, but there's nothing extremely offensive about them. So that's another thing to consider before watching the movie if you're not ready for that sort of content.
