HKT48 member Sashihara Rino (指原莉乃)'s 3rd Photo book will be released at 22 March 2016, and the title has not officially confirmed yet, but Amazon Japan's page shows its title is "Scandal Chuudoku" (スキャンダル中毒).
Note1: Scandal Chuudoku literally means "Addicted to Scandal".
Note2: In TV drama Majisuka Gakuen 4, the character Sashihara Rino cast is called "Scandal".
On the other hand, in another Japanese leading online store "Rakuten", the photo book's title is still showing "Title to be announced".
AKB48 producer Akimoto Yasushi mentioned the photo book's title called "Scandal Chuudoku" on 755, but it is hard to tell if it is the official title.
Sashihara Rino also confirmed the title "Scandal Chuudoku" (スキャンダル中毒) on her twitter, and wrote she really likes the title.
