Upcoming 4-member girl group 1PS (pronounced "one piece") will hold their official debut stage on 'M! Countdown' today, but before they do, they're here to introduce a bit of their upcoming sound with a MV teaser! 

They'll be releasing their first album 'The First Score' next month, and the title song will be "Because I'm Your Girl".

The girls show a very pure femininity as women who have fallen in love in the video teaser, continuing on with their jacket photos released earlier.

So check it out above and make sure you watch their debut stage tonight before the release of their music on March 3!
