That item does not ship to S. Korea so you should not have bid on it unless you had made prior arrangements with the seller (if you did make such arrangements remind him/her of it and request that s/he send an invoice with s/h). ALWAYS check in the Shipping and Payments tab that the quote you are getting for s/h is to your location (select your country from the dropdown and enter your zip/postal code if there is a blank for it once you have selected your country) before relying on it. South Korea does now show up in the dropdown (not sure why, worldwide shipping with exclusions but I don't see any exclusions that would exclude it; may have something to do with an item being listed on ebay.com--note that the price is in USD--while the item is in Germany).
You may be able to get the seller to create an invoice with s/h if you contact him/her and explain you relied on "Worldwide Shipping" and no stated exclusion of Asia or South Korea.
