I'm selling this because I found it while sorting through unwanted items at my parents' house. This is a book by the author Masaharu Taniguchi. ☑️ 20 Chapters on Invitation to a Happy Life It has stains and dirt due to aging and long-term home storage. The name has been erased on the last page. There may also be underlining, etc., but there is no problem with reading it. I hope that only those who understand that it is a used item will purchase it. Thank you for looking.
