I inherited a bizarre guesthouse with twelve rules written on the walls in blood.
"Keep quiet after dark." "Don't look in the mirror at three in the morning." "If you hear crying, pretend to be asleep immediately."
I thought it was just a marketing gimmick meant to sound mysterious, until the first guest broke a rule and vanished without a trace. The security footage showed him in his room all night, but by morning, all that remained was a pool of blood and a note that read, "You broke the rules." The scariest part was that I discovered the rules... were changing, one by one.
