Ping ball in 1973

The story was like "Listen the voice of wind" which be written by same writer Haruki Murakami.
In the story, 2 guys were appeared. One was called himself "I". And another one was called rat.
During I read it, I thought the 2 guys were same guy. I could't know whether it was true or not.
It was very strange story.

My lanking: ★★★☆☆
