The special Mnet show documenting the audition ran from May 22, 2009 to July 10, 2009 with a total of 8 episodes. The show's description indicated that the audition was seeking "the second Morning Musume" or "the second BoA".
Broadcasted on May 22, 2009. The three judges are gathered, E-Tribe, Jung Sungwook, Soulflower. The finalists perform in front of them and the judges gave their feedback. They were severely disappointed and said that none of the girls had what it takes to be a singer in Japan. Then the girls get split in two teams (A and B). Then the scene shifts, and it shows that both teams have to state their bads about each other. The girls aren't serious enough and the two MCs (Chansung and Junho) get mad at them.
Broadcasted on May 29, 2009. Team A and B get into a recording studio and get feedback from Soulflower. According to the judges, Team A is less skilled than Team B. Both teams stay in the recording studio. ℃-ute's Umeda Erika and Yajima Maimi pop in to observe and watch Team B. Then there's a performance day. Each team can only perform once. Tsunku says through a VTR that the keyword when performing is "smiling face" in Japan. The girls perform ℃-ute's Sakura Chirari and the judges gave their feedback. They said that although Team B's level has gone up (regarding singing and dancing), it was Team A that surprised them (was really energetic, worked well as a team). Then the teams are switched up: New Team A: So YuMi (leader), Oh MiNa, Jang Mikyung, Kim ChoHye. New Team B: Yang YunSoo (leader), Lee SuJin, Seo YeRin, Jang DaHyun, the two new leaders were chosen because they stood out the most to the judges.
