Oh my.. what a thriller cum suspense movie. One of the best K-movie of this genre I must say.

You will keep on guessing what might be the catch but till the very end you won't know.
So take my opinion over this, don't force yourself to pick up on any clues.. you won't get any.. in this process you will ruin the mood that the movie is going to set.
Just watch with a blank mind and enjoy this masterpiece.
Trust me.. i somehow resent myself for ruining it by thinking about the possible suspense in every 5 mins.

The acting the plot is mind boggling and will leave you amazed at its twist and turns.

The first 15 mins may seem like a horror genre and m not gonna lie.. there's a jumpscare as well to make you believe it to be one. But actually it's a thriller suspense movie so don't quit just because it scared you in the beginning! :D

Must watch movie!
