Throughout this drama, I had really enjoyed the dynamic between Yan Zhi and Man Na as they experienced an inverse development in their character arcs. I always see it as a clash between the natural genius and the determined hard-worker, eagerly awaiting at each episode at who would over-triumph the other. Also, as a protagonist's strengths can only be best exemplified with a strong adversary, the Japanese spy forces had definitely measured up to it.

Lastly, it was amazing as to how character decisions are shown to have impactful consequences that would result in a domino effect. The many twist-and-turns in this story are very unexpected and provides the suspense of a spy's life that really keeps you guessing. Definitely recommend giving this drama a watch!
