Don't have Spoiler

Until now, I'm very captivated by this drama.
The history is very addictive, since the first episode.
I'm thinking about what will happen in the next episode.
The plot is very carefully linked in all scene, the primary, secondary and tertiary is very connected and the same time is very unique.
I love the couple their complicity and relationship that start with confidence and friendship.
This drama shows how can a person change when having power, and how the power can destroy the humanity in a person.
