In the Surveillance Video, My Mother Got up at Three in the Morning to Cook.

[Programmer × Cyber Suspense × Split Personality, not a cool article, slow to warm up] In order to find out the strange intruder who lives alone in his late mother's home, as a top programmer, he uses code troubleshooting methods to pursue the culprit. However, before the system collapses as the time limit approaches, he discovers that the biggest suspect is actually his own sub-personality that split out of grief! The pace of this book is relatively slow. The protagonist is depressed and tortured in the early stage, but he becomes stronger little by little. Although it is not a mindless novel, it is consistent with the real situation.
