The inspiration comes from a comic book "Cruel Punishment: Confessions of a Murderous Police Officer". This comic roughly tells the story of Tan Haohui's "doing a good deed every day and feeling super high". Some of the cases mentioned Lao Tan's first love, including that Lao Tan had been secretly executed in order to enter heaven after death and meet Minamoto Giichi. I looked at the original part. The protagonist of the original work is a forensic doctor. Of course, the protagonist is also Lao Tan's first love brother Minamoto Reiji. The original work has a film and television work. After reading it, it inspired some of my imagination.
