In Haruki Murakami's "Sputnik Sweetheart," the protagonist expresses a deep sense of loneliness and disorientation. This feeling emerges when everything familiar is suddenly gone, leaving a void akin to floating in space without direction. The imagery of drifting like a lost satellite captures the essence of feeling unmoored and helpless in a vast, indifferent universe.

The comparison to a "little lost Sputnik" highlights the theme of isolation, emphasizing a profound disconnect from reality and the emotional struggle that accompanies such feelings. This metaphor serves as a poignant reminder of how personal loss can leave us adrift, yearning for stability and purpose while grappling with the unknown.
