The night before the college entrance exams, I got a message from my landlord: “Don’t open the door tonight. Don’t answer if someone knocks.” Then the entire building disappeared. I was sure I lived on the fourth floor, but the rules written on the wall said: “This building has no fourth floor.” The Rule Horror Stories had arrived. If someone knocks more than three times, do not open the door. If you hear marbles rolling late at night, don’t look up. If someone calls your name, no matter how familiar their voice sounds, do not answer... Anyone who broke the rules vanished from this world, and no one remembered them. While everyone else fought desperately to survive, I used my brain to clear the levels. The rules said not to open the window, so I tore down the entire wall. The rules said there was no fourth floor, so I went up there myself to see what was really behind that door. To everyone who cleared the level: welcome to the game. The college entrance exam hasn’t even started, and I’ve already cleared this building.
