Girl groups Sistar and After School will be coming back around a similar time.

Sexy girl groups After School and Sistar will be making their comebacks in mid-June around the same time and plans to perform on the same stage on sometime on the 13th to the 16th. Male fans are waiting patiently for the day of their comebacks.

An interesting thing to take into consideration is the fact that their partners have changed. Sistar has been working with Brave Brothers who created songs like, "Alone" and "Gone Not Around Any Longer". This time, Sistar has partnered with Double Kick, who have always been working with the group After School. After School on the other hand, partnered up with Brave Brothers.

Four years ago, After School worked with Brave Brothers to produce "Because of You", while Sistar worked with Double Kick last year to produce "Loving You".

After School chose Brave Brothers' new song "First Love" as their title song and plans to reveal a punky but lovely image. It will definitely be a change from their usual sexy and powerful performances.

Sistar has changed as well. Sistar wanted to do something that expresses their real colors. A representative revealed, "Sistar and Brave Brothers have been working together and some great songs have come out but we saved them for later. This time, Sistar will reveal some changes with a song from Double Kick."

The performances of these two groups will be a hot sensation to watch out for. After School is preparing for a recreation of a famous show in Las Vegas while Sistar is preparing their new "ring dance". June 4, a photo of Bora sitting on a ring was released as a teaser and heightened the anticipation.

Sistar will release their new album on June 11 and After School will release their song and music video on June 13.
