Whilst this may not be the first movie with the theme of a student falling for a teacher, it is certainly one of the more memorable ones. Gone is the 'cute' student and teacher relationship. Instead we are given a complex and raw relationship between two individuals who are unhappy in life. The storyline is not complicated but there are some parts where you do have to decode and look for the deeper meaning. Whilst some may find this frustrating and confusing, I found the symbolism in the movie really interesting and really added another element to a movie which has the potential to be cliched. Jo Bo Ah portrays the main lead as a chilling and psychotic character and showcased her amazing acting abilities. But she also had this ability to somehow still make you sympathise with the character and understand her to some level instead of just seeing her as someone who is crazy and obsessed. I loved how at the start of the film she was cute and flirty and as the movie went on she became more and more unravelled. Even at her most psychotic stages there was still a glimpse of that high school girl that was reaching out for help and for someone to love her. The movie kept me on the edge of my seat especially towards the end and the cinematography really added to the chilling atmosphere that some parts of the movie gives off. It's definitely one to watch if you like movies with dark themes and raw emotions.
