Adding their card to the list of September comebacks is none other than BTOB!

The boys are getting ready to release their 3rd mini album, and to make this news even more exciting, they've already put out their first batch of teaser photos!

These concept photos are supposed to go with one of the upcoming new songs called "When I was Your Man".

This song isn't the title track, but it almost was due to its said unique retro R&B sound. So to highlight this song, the boys have decided to pre-reveal the song over the radio, rather than TV broadcast, sometime next week.

This is a different promotion tactic from most idol groups as the idol market is usually very focused on the visual elements. However, BTOB is determined to have the song appeal to music lovers through its sound alone, and thus, has decided to reveal "When I Was Your Man" live on the radio ahead of their mini album release.

Specific dates haven't been announced yet for the live radio reveal of "When I Was Your Man" nor their mini album, so continue to check back for updates!
