Both female and male lead have a solid chemistry. The male lead pulled all the stunts and action scenes so well, his duality of being a cold-hearted in mission and being in-love is awesome. The female lead also did her part in the series and I think it worked. The story is fine from acting, props, and editing everything fits.I found out that only 2 songs were mostly used but I agree with the music director, it fits the scene so well. Thus, it intensifies the scene wherein you would feel it yourself vibe. Watching this is like a set of The K2. I also recommend watching that after this or before this!
