"The Science of 'Cheerful People' Whose Lives Somehow Go Well" Hideki Wada Price: ¥1380 (excluding tax) This is a book purchased from a used bookstore. Includes the obi (paper band). There is some wear and staining on the spine and the inside back cover (photos 4-5), but there are no stains or folded pages in the content pages. It has a paper cover from the bookstore, so if you don't request otherwise, I will ship it as is. #HidekiWada #Hideki_Wada #book #society/management
