The story was slow at the beginning because it needs to establish the character's direction and growth for the future episodes but after it reached a certain point in the plot (the death of a certain prominent figure), it starts to pick up the pace The one that actually made me stayed was how they protray loyalty in this drama...some drama shows how people betrayed friends for personal gain but in this drama, it showed the grey area of loyalty to friends of different background and loyalty to the country and its people...the finale scene just before the closure was a thriller The chemistry between the main characters were flunky and maybe a bit awkward at first but I think it was intentional to show the difference between two different people from technically different countries with different ideology, can help to understand one another by giving in and not succumb to ego This doesn't last long though, which is good, as the story progress, you can actually see the character growth of the main heroes/heroines. You can see they starting to understand one another and actually shore up each other's weakness and becoming the unstoppable duo... The side couples had better chemistry and is a breath of fresh air whenever they are on screen...at first, the main couple were kinda awkward to watch so the side couples were kinda what you want to look at but once the main couple had each other's back, you starts to enjoy both of the couple's romance arc The villain in this is top notch, a definition of villain and not some common thug...His sense of moral is what made him the devil incarnated due to his obsession with being at the top of every living things... This drama definitely require some patience, maybe after episde 4 or 7, the story actually shoots up in a hyperbolic way...
