Girl's Day has been getting fans excited for their comeback and now a teaser from "Expectation" has been revealed.

The ending credits of the March 9th edition of 'Star King' featured 30 seconds of footage from Girl's Day's upcoming music video. Just like they stated previously, the girls have done a 180 degree transformation from their cute ways as the preview features the girls looking lovely in black attire and showing off their sexy dance moves. The song sounds upbeat and very danceable as well.

The title track "Expectation" is an electronic dance song which expresses a girl's determination to catch the handsome guy she has her eyes set on and change his playboy ways.

Girl's Day's first full length album 'Expectation' will be released on March 14, until then check out the preview below!
