Kim Se Jung mentioned, "I once told Wanna One, 'It's a precious time now, so don't get into fights. However, during my days with IOI, I had to eat together with other members during promotions and at one point, that even became difficult."

She also commented, "While I was promoting back then, I remember Super Junior's Heechul telling me, 'Don't exhaust yourself'.  So I shared the same advice to Wanna One but now that I think about it, I can't look Wanna One in the eye without feeling embarrassed."
