Girls Day, the upcoming girl group that has been using flash mob tactics to promote themselves, is set to debut on July 9th. A teaser for the group has just been released, and it gives us an insight into what their debut concept is going to be!

From the looks of this (creepy) teaser, Girls Day will be taking on a doll concept. All I really have to say is that if you don’t like dolls, then don’t watch this teaser. It’s pretty creepy… While the teaser does show us a hint at the concept, it gives no insight whatsoever into the song type. Let’s just hope it’s not some cheesy and cute song. The teaser is below:
