Han Seung Woo, Choi Byung Chan, Lee Jin Hyuk, and Kim Woo Seok gained a lot of attention from their fellow trainees for being sunbae idols with debut experience.
During the interview, Han Seung Woo said, "I was the happiest in the world when I first heard I was debuting. I was excited thinking about how I can be on TV but I grew concerned as we released each album."
Lee Jin Hyuk shared, "There are so many groups but the ones that succeed are only 1 or 2 groups. I realized (success) doesn't happen just with hard effort."
Choi Byung Chan said, "(We were told) It's not guaranteed that we will do well even if we make a comeback."
Kim Woo Seok tearfully revealed, "To be honest, I blamed my agency in the beginning but then later I blamed myself, thinking, 'Am I not good enough?'"
In the level test, Kim Woo Seok and Lee Jin Hyuk performed "No Perfume On You" by TEENTOP, while Choi Byung Chan and Han Seung Woo performed "Save Me" by BTS.
