As mentioned previously, the legendary idol group are set for a comeback in February, and here to kick off the teasing process is the image you see above. In addition to the numbers 2015, we see '2015.02.', '12th Album', as well as the members dressed in T-shirts with letters that represent their first name. 

The parts of the teaser image that are raising questions though are the '?' and '*', which have the numbers '1.5', and '1.8' under them. These numbers are thought to be dates of January 5th and 8th, but we can't yet know for certain what will be happening on those days.

It looks like we will also get to see Andy, who had been hiatus, make his return with the rest of the members, so this will no doubt be a comeback fans will be counting down to!
