This is a manga my father was reading at home. It's 20 volumes, which complete Part 1, and a companion book, like a fan book, making a total of 21 books. I don't think there are any unreadable stains or damage, but I haven't checked every page. Please assume there may be small scratches, wear, and creases. Please consider these as used books. For some reason, volume 5 has significantly more page yellowing, so please be aware of that if you are concerned. This series has been made into dramas and movies in the past, and was remade a few years ago, so I think it's a popular series. I hope anyone who wants to read it as the original work will enjoy it. I haven't counted, but it seems there are some volumes with flyers from the time and obi strips from the era of Tomohisa Yamashita.
