Block B has recently announced that the group members will be forming unit groups. 

Subvocalist and "nothing else" Jaehyo and main vocalist Taeil are a singing duo, leader Zico, "visual" Kyung, and maknae P.O. are a rap group, and "smile representative" U-Kwon and dancer B-Bomb (Minhyuk) are working together to put together the most amazing performance in K-Pop history. 

As the debut of their unit groups come closer, each group is practicing as hard as they can, hoping to win a number one slot on the music shows. 

But U-Kwon and B-Bomb have a bit of a problem. 

B-Bomb's dance partner can no longer dance with him because she injured her ankle when practicing with her own dance crew, leaving him partnerless for the second time. 

Frustrated by the situation they are faced with, Cho PD and Block B's choreographer agree that the only way to solve this problem is by holding auditions to find B-Bomb's newest and hopefully last dance partner.
