Did not intend to watch this due to Park Shin Hye being one of the cast, she has spoiled many almost great kdramas for me so has become quite a turn-off. Decided to give this a go after seeing reviews for the drama. Personally, I felt that the synopsis for this drama did not give it justice, synopsis simply wasn't interesting enough for a click. Thank goodness for viewer reviews. Surprisingly, this was a very captivating and exhilarating ride, especially if you like playing RPG games. Each episode was a great hook. This drama would be perfect and better received with a different lead actress, in my personal opinion. But still, I give this a 10, kudos.
