4-member girl group 1PS (pronounced "one piece") held their official debut stage on 'M! Countdown' last week, but have now released their first music video and album 'First Score'! 

The title song of the album is "Because I'm Your Girl" for which they prepared a fun teaser. The girls show a very pure femininity as women who have fallen in love in the video. The choregraphy is fun and upbeat, a perfect combination for the Spring.

Check out their new MV above and let us know what you think!
