The first episode of the competition program finally aired on April 7. The broadcast showed the trainees participating in level tests. 

NU'EST members- Choi Min Ki (Ren), Kang Dong Ho (Baekho), Kim Jong Hyun (JR), and Hwang Min Hyun - appeared as Pledis Entertainment trainees of 6 years. Kahi, who was also formerly a girl group member under Pledis Entertainment's After School, broke down in tears after seeing the NU'EST members. 

She commented, "I feel so bad for them... They're so unfortunate..."

During the interview, Kim Jong Hyun revealed that he avoided looking at Kahi on stage to prevent himself from also crying.
