The title of the book will be the same as the serial title.
Extra parts include:
- a group cross-talk
- special gravure spreads; cool version and true selves version
The current release date for the book is set for July 19th.
Currently, I only know that it is available to be pre-ordered on Amazon, but I'm sure other websites will update about it eventually.
