Mamamoo Wheein raised expectations for her comeback by releasing the second concept photo of her first mini-album "Red" on her official SNS.

In the released image, Whee In grabbed attention by wearing a blue dress and showing off her elegant figure and seductive charm.

In particular, if Whee In predicted an unconventional transformation with red paint and provocative poses in the first concept photo released earlier, the second concept photo draws attention by comparing another charm to blue color.

Whee In, who has shown emotional ballads such as "I'm burdened" and "Let's break up," as a solo artist, heralded a different charm through this album, amplifying fans' curiosity.
