When I heard Kim Seohyung was in it, it was a yes for me. The woman sure picks great scripts and brings out the character next level. You will hate some in the beginning, love some in the beginning; however, in the end, it all completely changes. It s cleanly put together and executed, every actor is amazing to the point that it is chilling! The only reason that the music got a 9.0 was that I don't remember much of it. It's usually hard for music to make an impression on me unless it's the next level. But that is because I was so engulfed by the story itself!
