Su, born in prison, has always wanted to see the "crow" from the story her mother told her. On the day she was going to be secretly executed, Gill, an artificial intelligence with a database of everything outside the prison, was thrown into prison for a test run. Su develops a special feeling for Gill, not caring whether her words are programmed or self-conscious, and not trying to tell if she has human emotions. Unable to distinguish her own human feelings... in this small cell, the lonely Su got her first doll--she met a "person" who could comfort her soul.

After Ming Shu finished his training and returned to Dongye City’s Criminal Investigation Bureau, he found that Xiao Yu'an, his old neighbor who was like a big brother to him that left without saying goodbye many years ago, had suddenly become his immediate superior. What was crazier was that they also became housemates and started living together! While Ming Shu juggled that headache of a situation, mysterious murder cases followed one after another - an unemployed man suddenly going crazy in a book cafe, the most hardworking performer of a Chinese orchestra dying strangely, an escape room game that seemed to be more than a game... Ming Shu, ‘This time, I won’t let you go.’ (Source: Bilibili Comics)
