Jung Se Woon and Lee Gwang Hyun had the concept of going busking, and they both expressed the freedom of music perfectly in their shoots. Jung Se Woon said, "'Produce 101 Season 2' was a program that was like an essay question to me. Studying and reviewing for the test was a challenge every time. It's a precious time that won't ever come back, so I'm a little sad that I didn't get to show more during the live episode."

On writing his own songs, he said, "I believe the ability of a singer-songwriter is talent that comes from effort. I have to keep trying to express myself even in unfamiliar settings and work hard not to cower away."

Lee Gwang Hyun said, "I'm practicing singing, rapping, and dancing, and I still feel very lacking. But after going on 'Produce 101', my dream that seemed so far away became more clear. I was able to learn a lot and grow."
