"Six years ago, there was an old Marrow Hospital that was not well known to people. There was a big lake near the hospital, so it was often foggy. So people even called the hospital a fog hospital." "The hospital was experimenting with a variety of people it shouldn't. The head nurse who was helping with her work had suffered a lot of guilt. In the end, there was an incident in which he went crazy and killed everyone in the hospital, and himself committed suicide." "And now six years later, a rumor has started circulating on the Internet that the head nurse is still alive. The reporter goes to the fog hospital to dig up the fact." Is she alive?
