Not sure if it's worth the effort just for a book. I've double-checked, five copies available, the site ship to Korea and you should be able to order the book yourself from the link below:
I've proceeded buying it directly from a second-hand seller in Korea. No delivery fees. Need to improve my methods to buy things with sats here. Thanks for all your efforts. Have a few sats for the trouble.

I'm glad you find a local seller, much better!
