Stellar will make their comeback after 6 months.

On August 21st, Stellar will release new digital single "Mask" and will start off with a whole new promotion. Their lastest mini album "Marionette" attracted much attention and brought them much popularity due to the change in the group's concept and performance.

"Mask" is said to be composed by Sweetune who also worked on "Marionette" and penned by G-High. The agency said,"Stellar will be able to showcase both their dreamlike charm and elegance, as well as their sexy beauty through this new song"
