Well, this drama started off amazing. The plot was well written, and it was thrilling to watch and try to keep up with it. Despite the fact almost 100% of the cast are completely rookies, their acting was AMAZING, I could feel every emotion with them! The only point is that the story is extremely predictable, and what was the most thrilling plot ever, turns into a extremely cliche kdrama. I think it could have been better planned. Btw I don't rewatch dramas, that's why I gave it a low rewatch value.
