Despite some flaws in the story and unnecessary scene that drag the drama just to fill enough time (be warned, sometimes it felt like it was overused and repetitive);
The drama story was well written. As a gamer myself, I'm surprise that the writer was aware of how games and augmented reality work as he/she manage to blend both virtual and reality well while the protagonist need to solve a case. I like how the writer decide to stay true to the story until the end and not giving much of what audience want just like other dramas where most like abusing romance part to the point of annoying.
Overall, it is recommended if you like thriller dramas where its actually well written and not too focused on unnecessary romantic.
