From the story, acting, music, visual, etc is so good. This is also one of the drama I never fast forwarded because the value of lesson is so valuable. I learned from this drama is that decision, strategy, cautioness, mindset, communication, and mentality is something that we always needed when doing something to the best. And I think the best thing of this drama was the journey of each character and not just the lead but also the support role. Lastly I strongly recommend for those who haven't watch this drama to watch it.
