I rarely write a review. But this time it was essential. I had no plane to watch an horror drama but the trailer attracted me and since the first second i was captivated and couldn't escape a single moment. The acting is the best i have ever seen in any drama. The story is so engaging and unique and with a huge plot twist at the end. The music fits perfectly. The harmony between characters is unbeliavable . I loved every single scene part ... thanks sooooo much for such a wonderful drama now all my friends are watching it everyone as overwhelmed as me !!!
