When the group was asked, "Among G-Friend members, who would be chosen as the center for a sexy concept?" Yerin chose SinB, saying, "At the end-of-the-year festival, we danced to miss A's 'Bad Girl Good Girl', and SinB did really well. She bit her lip and gave an impactful performance." In response, SinB stated, "Even I was surprised when I saw that."
Who do you think would fit the sexy concept?
