No idea. It could be that it's my reading of this story but from what I recall of his other works, there is a quietness throughout: in the settings, the characters/characterizations and the action. In this one, the characters seem to me to be lonely throughout, especially with each other. They've each been isolated from one another by time, distance, memory, desire, expectations, etc.
I've often thought that I wouldn't want to meet certain writers whose work I've loved. The words on the page and the reader's own imagination can tend to conspire to create an idea of who a writer might be. Such a construct can be delicate and easily shattered by the reality of meeting in person. That said, I have no idea who Murakami could be and would jump at a chance to get a sense of the person behind the words.
