This is a good thriller with a nice, but not extraordinary, romance story. There is character development and a good portrayal of raw and intense emotions. Although Lee Ahn’s character’s development is progressive throughout the drama, the insistence of the premise that he lacks intellectual value really takes away from the greatness of his persona, leaving a sour note every time his dumbness is addressed. The drama has suspense, romance, some comedic moments, supernatural element, and tragedy.
