If you love both Japan and South Korea, this is your movie! What a delightful collaboration. We have suspenseful thriller between that develops entirely through the movie. If you are looking for the translation in English, you can watch in its entirety on Drama Fever. You do need to sit down and watch it without any distractions, as it can be hard to follow for some viewers. However, when the story comes to complete fruition, 00:00:00:00, you will gain complete appreciation. Music gets a 5 only because well, there isnt really an OST. Its just instrumental, albeit wonderful instrumental. This all around gets 9.5 for me. It is an amazing movie that I suggest everyone check out!
