During the show, Kang Sung Hoon discussed his pink hair, saying, "I didn't want to have pink hair, but after I signed with YG Entertainment, I went to the hair salon, and it was already decided." 

He added, "The hair salon director had already selected the color after I joined YG...I was scared. I thought, when I should be gaining fans, I will lose many of them. I was really nervous, but now that I have pink hair, I think I look pretty good."
