This was a much awaited k drama. I have always loved Phs and Hhj acting. I had been waiting for their comebacks for so long. Phs's comeback was more special as it is the first show he is doing after his military service. For Hhj, I loved her previous work. Since this drama has 12 episodes, it is fast and straight to the point. The first episode itself was very progressive and engaging. It has a good mix of thriller, aesthetically pleasing shots, good storyline and a loveline. Overall, good source of entertainment with a dose of the present reality as it deals with the harmful effects of the blooming pharmaceutical companies, negligent governments, the growing diseases and the possible adversities that one can face in their lifetime with COVID becoming a reality itself, many years after a movie on similar issue was made.
