The book is structured around proportional scales derived from real-life social privacy distances (0m / 45m / 120m / 360m / 750m). The content is divided into five layers: general distance, polite distance, private distance, intimate distance, and negative distance.

As the content gradually moves toward more private realms, the color palette within the book transitions from vibrant tones to pure black, symbolizing the decreasing relevance and personal significance of information. In sections involving private content, newsprint paper is used, referencing the visual and material characteristics of mass media that disseminate public information. This choice metaphorically reflects how private information is continuously uncovered, explored, and circulated, causing originally confidential personal information to become publicized and consumed in ways similar to public news.

Through the integration of proportional structure, visual language, and material strategy, the book aims to present how the attributes of information shift as it becomes increasingly accessed and disseminated. As information is approached and obtained through continuous exploration, its privacy gradually weakens or even dissolves. At the same time, the book reveals how curiosity drives individuals to repeatedly cross informational boundaries. However, the secrets and information obtained through such exploration often hold little genuine meaning for the individual. The overall structural arrangement of the book seeks to encourage viewers to reconsider informational safety boundaries and reflect on their own roles and responsibilities in the act of acquiring information.
