Netflix originals can always be a hit or a miss, but this was so good in my opinion. The only reason it's not a ten in my book is that there were a few things left unanswered/things I would've liked to delve more into. The acting was almost too good, to the point I was uncomfortable with some scenes. Now that being said this drama is not for those with a faint of heart!! It's super gory and has quite a few triggering scenes (animal murder, graphic murder, rape, etc) but what can you expect from a Netflix show. Now what surprised me the most was the amount of sex scenes in the show, and they were SUPER explicit, especially for a k-drama! Their was almost a sex scene in every episode, if not multiple in one episode ( I think one went on for like 7 minutes if not longer, which is pretty long for me lol) Maybe it's just because I'm not use to seeing those type of scenes in Korean dramas . The chemistry between the two leads was also sooooo good, I would definitely be pleased to see them in another work together. If you're looking for a good psychological thriller, with a really good plot then give this a try!
