Kind of ridiculous that forensics didn't find a single hair, finger print or the ear stud when they checked the crime scene in the beginning. The identiy of the killer really just was the most basic solution.
I usually watch a lot of horror movies, especially B-Movies and true crime stories but this was just awful. Horrible writing and acting, over the top sexual content and violence. Especially the ending was just ridiculous. Horrible movie, not recommened.
Jo Hye Joo was great, she needs a main role soon.
