The young and naive Sumire is in love for the first time in her life, so it did not matter if the object of her affection is Miu, an older married woman. Though Sumire tried to justify her attraction as a mere admiration, there remained an inexplicable feeling that brings Sumire an excitement and drive to have Miu's affection.
At a glance, the two makes an unlikely pair: Sumire is twenty-two, a college drop out and a struggling novelist; while Miu is thirty-nine and running a successful business on imported wines. Miu is methodical and sophisticated. Sumire is sloppy and dissolute. Miu is clearly out of Sumire's league, so to speak.
There is, however, a common interest between the two, and though it is only one, it proved to be strong. On the first time Sumire and Miu met, they talked about classical music, and before their first meeting ended, Miu offered Sumire to be her personal secretary.
Sumire took the opportunity despite her doubt on her abilities. Sumire changed to gain Miu's affection; from wearing oversized clothes, she became presentable; from a chain-smoker, she became a non-smoker; and from an obsessed writer, she stopped writing. The transformation bothere Sumire that she called her situation a 'defection', then finally confessing her feeling of loneliness and confusion:
"'Sometimes I feel so - I don't know - lonely. The kind of helpless feeling when everything you're used to has been ripped away. Like there's no more gravity, and I'm left to drift in the outer space with no idea where I'm going.'
'Like a little lost Sputnik?'
'I guess so.' "Sumire confided all her thoughts to K, her only friend and also the story teller in the novel. They both love fiction, and talk in metaphors. K reads Sumire's writings and hangs out with her even in the wee hours of the morning. Obviously, K loves Sumire in the same way that Sumire loves Miu.
The story revolves on the complicated love triangle that is webbed by unrequited love: K loving Sumire, but Sumire loving Miu. Instead of pleasuring readers with warmth and love, this novel presents an overwhelming feeling of rejection and loneliness.
The characters' sentiments and acts makes this novel absorbing and affecting. With characters emotionally wallowed and pained, one would expect them to act and fulfill their longing. But exactly like how ordinary individuals would do, though puzzled and grieving, they stay practical, detached, and go on with their lives like nothing happened, giving this novel that painfully realistic touch.
" 'And it came to me then. That we were wonderful traveling companions, but in the end no more than lonely lumps of metal on their own separate orbits. From far off they look like beautiful shooting stars, but in reality they're nothing more than prisons, where each of us is locked up alone, going nowhere. When the orbits of these two satellites of ours happened to cross paths, we could be together. Maybe even open our hearts to each other. But that was only for the briefest moment. In the next instant we'd be in absolute solitude. Until we burned up and became nothing.' "Sputnik Sweetheart has the usual Murakami effect, with ordinary people living their ordinary lives suddenly trapped into what seems like an alternate, parallel world. In the story's beginning, Sumire is caught in love with Miu, a contrast to her sloppy and hermit life. On another turning point, K finds himself in an idyllic Greek island, bathing in the sun, a scene that is far from his dull life as a school teacher.
To enjoy this novel, readers should keep an open mind about the possible existence of a parallel universe. In other novels, all the metaphors would have remained as metaphors, but Murakami blends a realistic world with an alternate universe, turning some of the supposed symbolic and metaphoric things as literal, real occurrences. Through this different view, the mundane reality is put in contrast with the infinite possibilities that the alternate world offers. According to the novel, it's a place where our lost, isolated characters find love and clarity, where the characters' metaphors are alive, where K and Sumire's longing are fulfilled, and where too Miu lost a part of herself.
With no definite ending, and a writing style that is simple yet mysterious and profound, this novel can be read and felt repeatedly. Each reading will give a lingering feeling of sadness, drawing readers into deeper thinking on loneliness and longing. This novel is for those who seek to understand the limits of relationships, companionship, and of life in general.
