In Haruki Murakami's "1Q84," the author explores the duality of existence through the interplay of light and shadow. He suggests that these concepts are intrinsically linked; one cannot exist without the other. This idea signifies that all experiences and entities in life are balanced by their opposites, emphasizing a deeper philosophical understanding of morality and existence. The profound relationship raises questions about the nature of beings, particularly the mysterious 'Little People.'

Murakami points out that these enigmatic figures operate beyond human comprehension of good and evil. They have coexisted with humanity since ancient times, predating our simplistic moral frameworks. This implies that the Little People may embody complexities and mysteries that challenge our traditional views of morality, suggesting that understanding them fully may be an unattainable pursuit. Their existence encourages contemplation on the nature of reality and the unseen forces that shape our lives.
