The AOA girls talked about many a great things with MC Yoo Hee Yeol on the May 20 episode of 'Sketchbook,' including which members they would like to team up with to form a unit and what kind of unique concepts they would like to try. 

AOA has already formed three units in the past, including AOA Black, AOA White, and most recently AOA Cream. Jimin joked, "I would like to team up and form a unit with the tall Seolhyun and Hyejeong and stand in the center."

While everyone wanted to form units, ChoA had a different kind of ambition altogether. She said, "Everyone wants to do dance or hip hop units but I want to go solo," picking Primary and Yoo Hee Yeol as the producers she wants to receive songs from.
