Book off

“Book off” is a chain store selling second hand books or manga or DVD or DC in Japan.

I often go to a store in my neighborhood which has a small foreign books corner.
I have bought paper backs in English several times there and sometimes the books made me wonder what kind of person who sold those books was.

The book I bought the other day was a chinese novel translated into English but I’ve never heard of the author’s name or the book title.
When I got home I checked the book on the internet.All books by the author haven’t translated into Japanese.

I guessed the person who had had this book might have been a Chinese, but if she ( or he) was chinese it wouldn’t need to buy an English version of the book…or just a Japanese who can read English and like books ?
