B2ST announces their comeback with a mysterious teaser image

B2ST has announced their comeback!

The boys haven't had much activity in the beginning half of the year, but now they've released a mysterious image for their comeback! The image doesn't give us much except that the boys' 6th mini album is 'coming soon'.

The image also features an upside down A, and the Greek letters delta and sigma. 

There's no date yet, but stay tuned for more information!
