?SISTAR announced their comeback yesterday, and we already have Bora's teaser image!

In the teaser photo, Bora looks stunning in black, sitting gracefully on a ring. The photo seems to hint that they'll have a darker concept like "Alone" instead of "Loving U". 

Along with the photo, Starship Entertainment tweeted, "SISTAR's 2nd full album release D-7! Before our release, we're giving you a sneak peak of Bora's ring dance^^~ Look forward to SISTAR's new album on June 11!!"

As we patiently wait for their 2nd full album release on June 11, stay tuned to allkpop for more SISTAR news.
