IOI were one of the groups to guest on the September 2 installment of 'Sketchbook' for the show's girl group special, and the girls got brutally honest about "Pick Me," the track which had placed them on the edges of fame.

Despite its popular among the masses, "Pick Me" wasn't much of a hit among the IOI members themselves. Choi Yoo Jung confessed, "I was worried about whether the song would do well. I didn't think that the program itself would do well, either." Pinky was even more blunt, saying, "When I saw the dance video, I thought, 'We're done for,'" bringing laughter. 

Well, lucky for IOI that both the song and the program did incredibly well!
