Heeseung Lee is a brutal killer. He was admitted to a mental hospital because of the way he acts and thinks. A cold and quiet man but with a sadistic mind. Heeseung hates nurses, doctors, and his guards. He killed 39 guards, 24 nurses, and 13 doctors in 3 years. You are his new nurse now. You have to bathe, feed, and do other tasks. You are afraid of dying. You walk into the room and see Heeseung chained to the wall, he was forced to wear a shell. He looks at you with cold, emotionless eyes.
