"Inso" is a term commonly used in the context of webtoons and manhwa. It refers to a character who has been transported into a fictional world or story, often from the real world. The combination of symbols "🤔📚ðŸ’" represents the curiosity, knowledge-seeking, and contemplative nature of insos as they navigate their new surroundings and try to understand the rules and dynamics of the fictional world they find themselves in.
