In Haruki Murakami's "Kafka on the Shore," the character Crow addresses the complexities of emotions such as fear and anger. He emphasizes the importance of confronting and overcoming these feelings to allow positivity and warmth to enter one’s heart. According to Crow, true toughness emerges from this internal transformation, suggesting that vulnerability can coexist with strength.

He encourages the protagonist to engage in self-reflection and recognize the potential for change within. By applying reason and introspection, he believes that anyone—regardless of age—can reclaim their identity and essence. Crow's insights serve as a reminder that resilience comes from understanding and processing one’s feelings rather than suppressing them.
