In this era of rampant electronic reading, Su Mian is a proofreader of old manuscripts living among old papers. She has a pair of eyes that can see "word bleeding" - it turns out that all the typos in the world are the unfinished last words of the dead. Every time she corrects a word, a soul can stay for one more minute, but the price is her own memory.
Until she met Bo Yan.
He is an extremely wealthy chaebol leader, and he is also an "illiterate" who can't even write his own name correctly. Su Mian was horrified to discover that Bo Yan was not a human being. He was the biggest logical bug in the novel called "The World" and the biggest typo in the world.
Correct him, and the world will restart and Su Mian will disappear; if you don't correct him, the world will collapse and all things will die.
The crazy criticizing man put the correction pen against his heart, smiling paranoid and affectionately: "Mianmian, change me, or accompany me to write this rotten world to its finale."
