After his sudden death, Lin Cheng became an "observer" - able to see all the strange rules of action.
Class F, Class D, Class S. Those who can kill, those who can bewitch, and those who can distort reality. In his eyes, they are all lines of text that can be disassembled.
He has no superpowers, only a pen that can't write, a broken mirror, and a portable space that only he can open.
But he has logic.
And weird, most afraid of being understood.
Product managers teach weird people online how to be a human being - no, be a ghost.
