Haruki Murakami said this quote

I'd swallow some whiskey and listen to the waves while I thought about Naoko. It was too strange to think that she was dead and no longer part of this world. I couldn't absorb the truth of it. I couldn't believe it. I had heard the nails being driven into the lid of her coffin, but I still couldn't adjust to the fact that she had returned to nothingness.
