An absolute impeccable masterpiece. It is the best that kdramas offer. The entire crew and cast did a phenomenal job. It is by far my favorite series. The acting was brilliant and the writing was splendid. There were so many jaw-dropping and thrilling revelations/moments from the drama that could make you feel a range of emotions: contempt, sadness, empathy, anger and exasperation. So much was going on in each episode and each moment/scene was unraveled silently and calmly but yet full of suspense.

The way the protagonist was treated was heartbreaking and you could only hope that she and all the other victims involved get the happiness and justice that they deserve. The story was unfolded unexpectantly. Although the revenge plan was an excellent one, outside circumstances take place to a level I did not expect.
All I am saying is that you will enjoy every moment of this series. It makes for a fun watch. You will gasp in astonishment with each revelation revealed.

Enjoy!!
