The teaser video of the song "Erase" where Hyorin and Joo Young kiss was released.

On November 17, Starship Entertainment posted on their YouTube channel a teaser video of Hyorin and Joo Young's duet song "Erase."

In the video, the two exchange looks at a bar.

The agency said, "Hyorin plays two roles in the 'Erase' MV and she switched back and forth between a chic and cold city girl to a sophisticated and sexy girl, and Joo Young perfectly portrayed the image of a bad boy."

Hyorin and Joo Young will have their comeback on November 20.
