Weird Talk About Rules: I Can Nail the Rules for Three Seconds

At one forty-eight in the morning, the notice in the elevator was changed. Blank paper. Scarlet letter. There is only one. "Please do not look directly at the elevator mirror for more than 3 seconds after 22:00." Lu Yi looked at it. In the third second, the person in the mirror blinked first. He reached out and pressed the line of red letters. The reflection stopped. Three whole seconds. The price has come. There is a gray-white scar on the back of the hand. Then, he forgot someone. In the chat box on the top of his phone, the girl called him "brother." She made the dumplings in the refrigerator, kept the porridge in the pot, and wrote the note in the crack of the door. But Lu Yi couldn't remember who she was. Until the name 402 began to fade on the property roster. Until 2:17 in the morning, an old floor lamp lit up on the non-existent fourth floor. Only then did he know—— Her name is Lu Yuan. It's his sister. And the entire apartment building is erasing her from everyone's memory. Others can only follow the rules. Lu Yi can nail the rules for three seconds. The problem is, with each nail, he remembers the person a little less. When he finally rescued her, did he still remember why he rescued her?
