To begin with, it's hard to categorize this drama. It's definitely not romance but it borders with psychological and thriller. The first episodes give a totally different vibe from what you will get later. The show begins on a lighter note but quickly turns dark and disturbing. The plot is pretty unique but feels too stretched, 16 episodes would have been way better. There are a few interesting plot twists, but it's just not enough to make this show outstanding on any level. If you are looking for something new and refreshing this drama is a good pick, but it's not that entertaining. The acting is only okay and the characters stay distant, most of the characters are not introduced that well. Overall it's a mediocre show. At first, it's even hooking because you want to find out what the heck is going on, but later that element gets dull because it's stretched for too long. The ending seems a bit rushed, they are building the atmosphere almost for the whole episode and everything happens during the last 10 mins.
