Posting because I can't even get a Korean copy online (all the websites need Korean credit cards or Korean ID to buy), the original newspaper it was serially published in is paywalled, and the only alternatives are an audiobook version on YouTube and a not so great Chinese translation PDF on Anna's Archive (currently in the process of OCR-ing and digitizing if that's the right word)
If anyone knows a way to either buy the book or if someone already has it and wants to sell (hell if you have access to original papers even), please let me know!
Definitely not available where I am, I've checked all in my area
