Story background: Longcheng, a southern city, ranks among the top ten in the country in terms of GDP and crime rate. There are two sets of operating logics in cities: those on the table and those under the table.
Archives Bureau: It's not a mysterious organization, it's just a business. Specialized in "disappearing" people - faking death, rebuilding identity, erasing the past. Clients include businessmen evading debts, witnesses hiding from enemies, and ordinary people who want to start over. It has been in existence for thirty years without incident, until now.
Lin Eucalyptus: Private detective, lazy, venomous, outrageous fees, and won't take the case if he can. There is a serious "compulsion to complete" - as long as the case you take is too bad, you have to finish it. The death of his partner five years ago made him stop where he was, not because of his deep affection, but because he made a choice at that time. He was not sure whether that choice was the right one. This matter made it impossible for him to move forward. He is not a hero, he is just an ordinary person who cannot let go of "no answer".
Shen Ji: A criminal police officer who is rigorous, realistic, has a strong sense of rules, and is easy to compete with. Her sense of rules is not innate, it is because she needs a set of logic to explain why the world is like this after her father died. It's not that she doesn't know that rules are sometimes used to protect bad people, she just hasn't found anything better than rules to rely on. When she investigates her father's case, it's half love and half - she needs to know whose daughter she is.
Intention: People must always reconcile with themselves.
