While verifying a marriage contract at the Contract Office, Chen Xiaoman discovers inconsistencies in the paper, seals, and registered identities on a document.
One marriage contract leads to old paper, land deeds, household registers, account books, and case files that were stored in the archives years ago. Each document can shed light on some of what happened, but none is enough to deliver a verdict on behalf of everyone. Some pages are missing, some annotations are unsigned, and some names have been reduced to half a stroke. Chen Xiaoman must trace each document's origins, dates, and handling records, confirming step by step what they can actually prove.
Joining her is Zhao Aning, a clerk in the Inspectorate. Chen Xiaoman excels at verifying facts through paper, handwriting, seals, and formatting. Zhao Aning is better at questioning the living and discerning what lies behind their words, and she understands the consequences a document can have for the people it concerns. They complement each other, but also keep each other in check.
As the investigation draws them closer, their partnership in official matters grows into familiarity, while trust becomes more complicated with every choice they face. The hardest questions are not just about the names in old cases, but also about who has the right to decide what another person should know, endure, and where they should go.
Theme: Documents and institutions can record facts, but they cannot decide the future for those who are still alive. When rules, truth, and real circumstances clash, people should retain the right to make their own choices. Through investigating cases and growing closer, Chen Xiaoman and Zhao Aning gradually come to understand that true trust does not mean taking on everything for the other person. It means respecting boundaries and giving each other back the freedom to choose.
