In Haruki Murakami's "Sputnik Sweetheart," the protagonist experiences a profound sense of loss that leaves a void within her. The imagery of an "empty shell" captures the essence of her diminished state, emphasizing how something vital has vanished from her existence. This absence becomes a haunting presence in her life, symbolizing the deep emotional impact of the loss.

The narrative explores the theme of absence, showcasing how Miu, a central character, grapples with the reality that an essential part of her has gone forever. Rather than a tangible sense of life, she is left with the lingering effects of what once was, illustrating the weight of unfulfilled connections and the lasting scars of emotional experiences.
