B1A4 have fans on the edge of their seat after they released a teaser for their imminent new comeback track.
The boy band released a 16-second video teaser for their forthcoming single "Sweet Girl" via their YouTube channel.
Set for release on Monday, August 10, the jazzy-colorised, retro-styled video clip features the B1A4 boys bracing themselves before a mic as they prepare to sing to their subject of desire -- a "Sweet Girl" who appears briefly in the teaser drawing the gazes of the boys onto her.
Band leader Jinyoung, 23, wrote the lyrics to the upbeat track himself, describing a guy who confesses his feelings to the love of his life.
Some lucky fans got a live preview of the song ahead of the group's official comeback after B1A4 performed "Sweet Girl" for the first time on stage at a guerrilla concert in Seoul on Thursday, August 6.
