A special surprise might be in store for BTOB fans soon.

On February 17, seven-member K-Pop idol group BTOB made a comeback with their fourth mini-album, Beep Beep and the title track of the same name.

During their comeback showcase on February 17, member Changsub made a rather intriguing statement.

"If BTOB wins #1 with 'Beep Beep', I will shave my head out of a resolve to start anew," he exclaimed adding, "On my forehead, I will write 'Renewed'."

The other six members seemed supportive of the goal and suggested filming the shaving process. "What do you think about filming a video of you shaving your head like Won Bin in the movie The Man From Nowhere?" they teased.

Pleading with the fans in the audience, Changsub urged, "Help me so that I can shave my head and film a video like Won Bin in The Man From Nowhere," to which the crowd responded with laughter.

Named last year's Next Generation Star at the 27th Golden Disk Awards, BTOB has a solid chance of making Changsub's bald-headed dreams come true.
