While I started reading very enthusiastically, I had to put the book on hold for quite some time because of time limitations, but I’ve now resumed reading it as part of the Read every day challenge. By lucky coincidence three other people will be reading the same book at more or less the same time. Just thought I’d write it here in case you were interested 
It’s not a bookclub or anything official like that, but everyone posts what they’ve read and sometimes a comment or two.
Thank you for the info. I went to a Japanese bookstore last month and flipped through one of them and felt I’m not up to it yet. I am now reading Show me your books! - #192 by lkyvic さくらももこ.
