Nogizaka46’s Saito Asuka, who seemed to be losing her job as an exclusive model for CUTie due to the magazine’s suspension, has been offered to become a regular model for Sweet magazine starting November 2015.
“As a fashion model,she belongs on a magazine,”says the editor for Sweet.
Saito will join the ranks of Namie Amuro and Ayumi Hamasaki, who have all become cover girls for the magazine in the past. Currently, Kojima Haruna, Rola etc are the cover models for Sweet.

Is there a reason the magazine is folding other than poor sales?
I am not sure but the fashion magazine industry is very competitive and CUTie is one of those unknown ones, not surprised if its closing because of sales.
