One day, internal medicine doctor K brought the medical chart of a patient named RUMI and said curiously, "Well? Isn't she an interesting case?" On the surface, she appeared to have nothing more than a common cold. When I pointed that out, K gave a cold smile and said, "Let's use room 909. I want to hear everyone's diagnosis on this particular patient." However, that hospital room didn't actually exist. K was a sexual deviant who lured his desired female patients into a hidden underground ward, where he imprisoned and tortured them.
