The other upload is the SP only pages from the bonus rewards, but lacks the main doujin itself. There are 4 missing pages in total, and the main doujin has lingerie while the SP pages do not. I initially refrained from uploading this because I saw it was already uploaded, but was notified by email that it was an incomplete version.
