Mari was born and raised in Korea, but her parents are from Nepal, and at times, she feels like a drop of oil in water, not quite fitting in anywhere. In this story, the author focuses on Mari, a protagonist grappling with her identity and sense of belonging. However, the book avoids portraying migrant children and their families with a negative or pitying tone. Instead, it highlights the pain and joy they experience as members of our society, regardless of race or nationality, through the narrative of one child’s journey.
