So recently a new girl group (AOA) released some teaser videos of their upcoming debut single "Elvis" (I think it's called Elvis haha)

Don't know anything about this group though.
All I know is that they come from the FNC. Entertainment, that they will be a band and that they are 7+1 members. 7+1 you wonder? Well, here is the story:

They are 7 angels (members) in this group - Seolhyun, Choa, Hyejeong, Chanmi, Yuna, Mina, and Jimin.

The "+1"-member is Y who is said not to be an angel, rather a half angel unlike the others who are introduced as angels.
The story so far of the group has been told as, “The seven angels always looked into the human world through their crystal ball and loved people’s music. One day, Y, the gate keeper, out of curiosity, opened the gate heading to the ground and came to earth with seven angels.”

I really like how they kind of showed this story in the Teasers xD
But yeah, so this whole "half angel"-thing is (according to a youtube comment) something about Y not doing all of the typical idol stuff like singing and dancing. She will be the drummer and that's about it (How can she dance if she's a drummer? So it does make sence).

They will have their debut stage on July 30th. So stay tuned!!!
