Please provide me with the context of "I thought it's a common possession Chapter 31." I need more information to understand what you're asking for. Specifically:
- What book or story is this from? Knowing the title is crucial.
- What is the nature of the "common possession"? Is it a physical object, a shared experience, a shared skill, or something else?
- What kind of content are you looking for? Are you looking for a summary of Chapter 31, an analysis, a discussion of its significance to the overall story, or something else?
Once I have this context, I can provide a helpful and detailed response.
