Mainstream society’s attitude toward immigrants has not changed, although the number of immigrants is increasing in Korea. As micro-intervention has been proposed as a strategy to cope with micro-aggregation in the North America, this study expands the concept of micro-intervention to Korean society and proposes seven types of micro-intervention, applying narrative models. Through theoretical literature research, the concepts of micro-aggregation and micro-intervention were summarized in the North America, and the processes of related subjects and narratives change were examined based on semiotics. Specifically, seven types of narrative models for micro-aggression and intervention were presented with the background of a Korean business case. Ultimately, this study shows that micro-intervention is a possibility and process of transforming their narratives through interactions between various subjects such as mediators, targets, perpetrators, collaborators, and bystanders. This study is expected to contribute to providing foundational research on micro-intervention against micro-aggression by proposing narrative models in the context of Korean society.
