The first two episodes are full of suspense. I cant sit still while watching it. I bet the rest of the episodes will give me high blood pressure and heart attack. So, I decided to wait for the final episode on the August 20. LOL. After all, the scripts and the actors all are well-chosen. Especially Ji Jin Hee, somehow his look, height and action suitable with the characters very much. Looking forward to the ending and I hope he will return to his normal life, being a professor.
