In Haruki Murakami's book "Yesterday," the narrative explores the complexities of human behavior and relationships. The quote emphasizes a common tendency among people to avoid straightforward paths in life, often opting instead for more complicated routes. This reflects a universal struggle with decision-making and the pursuit of meaning in one's journey.

The characters in the story embody this theme, as they navigate the intricacies of their choices and the emotional consequences that follow. Murakami's insight suggests that such detours are an inherent part of the human experience, encouraging readers to reflect on their own life paths and the reasons behind their choices.
