Sunmi is slowly revealing more and more about her comeback!

On February 14 KST, the solo artist took to her personal Twitter account to share two concept photos as 'spoilers' for the comeback. "I can hear the tails/sides of eyes and lips lifting from here," Sunmi tweeted, a reference to the tight winged eyeliner and 'lip piercing' she sports in the images. She then added the hashtag 'spoiler' in both Korean and English, raising anticipation with fans as teasers for the comeback have yet to be released.

Meanwhile, the official countdown will begin on February 15 with the album's tracklist, with various teaser photos and videos being released until Sunmi officially comes back on February 23.
