B1A4 Have a "Lonely" Winter in MV Teaser

B1A4 is all set to start the new year with a bang! After releasing magazine inspired photos for the jacket images of their new album to kick start the year, the boys have just dropped the teaser to their comeback song, “Lonely.”

The video doesn’t reveal much of the song and only hints of a sad ballad while the boys are bundled up and brooding in the cold winter in different scenes.

“Who am I,” B1A4’s second full-length album, is set to hit stores on January 13. Check out the solo and group jacket images the boys released on New Year’s Day here in case you missed it.
