On July 13, good news of the comeback was delivered along with teaser images on the singer's official social media channel.

In the photo released, the Sook-haeng not only boasts a more colorful visual, but also reveals an alluring and elegant atmosphere.

In particular, the confident facial expressions and gestures of Sook-haeng, who also boasts a solidly built body, and the phrase "Why Not" are also adding to the curiosity about how she will take off her veil.

Sook-haeng had earlier predicted an energetic stage with the words "Increasing her injury, preparing for a new song," raising expectations for the change.
