HaHa is all out to promote his wife Byul’s upcoming single.

On May 27th, a teaser video for Byul’s “You’re The Best” was revealed. The teaser shows a man wearing a bunny mask who strolled around Seoul handing out piece of paper that reads, “You’re the Best. Byul and Booto”.

At the end of the video, it was revealed that the mask man was none other than Byul’s husband, HaHa, who is working hard to promote the single. In addition, the couple’s close friend Lee Kwang Soo makes a cameo appearance in the teaser.
