Members Ye In, Yoo Min, Cha Hee, and Yeo Eun captivated the audience with Meloday Day's first album cover and amazing visual image.

On October 1st, Melody Day released its first jacket image for their third single "Speed Up" through all their social networking sites as well as their official homepage.

Releasing six photos, two group photos and four individual ones, the group's concept seems to be following a mature or "coming-of-age" look as they wear smoky makeup on and black high heeled boots. 

In the past, Melody Day had shown a very fresh and perky side of a woman in her 20s. With "Speed Up" the girls seem to quickly mature with this new sexy and sophisticated concept that fans sure will anticipate.
