It is such an awesome movie. Both the story and the acting in the movie is perfect. You will be on edge the whole time, and the plot twist is very well done. I think the soundtrack to the movie could have been better, though it didn't bother me as much, since I was more interested in the story and acting. While watching it you will differently be fangirling over Woo Bin and Hyun Woo ;) I recommend it to everyone! So much worth the time! <3
