Broadcasted on January 18, KBS2TV 'Happy Together 3' featured Gugudan's Kim Se Jung sharing advice she once gave to Wanna One members.
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."
