The Starship Entertainment trainees from 'Produce 101' posed for 'Singles'.
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."
