On June 21, 2027, Fu Xiran died.
This lonely man who suffered from bipolar disorder committed suicide by adopting Wu Yu from a loving home in Jun City seven years ago on Wu Yu's eighteenth birthday.
The diary left by Fu Xiran allowed Wu Yu to accidentally return to Renbei City twenty-six years ago. It has been regarded as an unsolved mystery by the academic community. It is far away from the natural earthquake zone, but a rare 8.5-Magnitude earthquake occurred in the earthquake source area, which completely disappeared from the world at the end of 2004.
Wu reunited with Xu Xingzheng, a student in Class 11, Renbei No. 1 Middle School, and met Fu Xiran, the 25-year-old new class teacher who joined Class 11, Renbei No. 1 Middle School.
After Xu Xingzheng's mother paid a large sum of money to Fu Xiran, Wu Yu was fostered in Fu Xiran's home, and thus discovered Fu Xiran's special side job - catching ghosts.
Fu Xiran, who has no close friends or colleagues, looks gentle and kind, but is actually cold and aloof, puts money first, and insists on being alone in everything. He carries with him the painful growth experience of his youth, but Wu Yu is uncontrollably attracted to him.
The ensuing series of supernatural events that occurred in Renbei City seemed to be related to the 11-digit numbers recorded on each page of Fu Xiran's diary——
Nearing the last page of the diary, which was also the eve of the earthquake, Xu Xingzheng's soul consciousness, sleeping in Wu Yu's body, gradually awakened. Wu Yu, who knew the truth about Fu Xiran's suicide behind the numbers on the last page related to Xu Xingzheng, began to try to prevent this unknown unnatural supernatural earthquake from happening.
