As the biggest self claimed fan of Park Shin hye, I was bound to love this movie anyways, but no one can deny its such a thought provoking movie, very well directed, all the actors did amazing park shin hye and jeong (I'm so sorry I just can't remember the name). The movie is a must watch especially if you're into horro/thriller/slasher/suspence movies, so worth it the ending unlike everyone else was quite satisfying for me, they showed both perspectives and the fact that it could just go on and on like a loop, so amazing, worth your time and you get to see the lovely park shin hye before sisyphus, just a win win for everyone
