On the September 28th broadcast of MBC's 'Human Documentary', Crayon Pop recalled the days when they performed on the streets with their bright training suits and held up signs saying they're singers, anything they could possibly do to get their name out there.

Ellin recalled, "Our members were so cold that our hands and faces became red. Other groups get to practice in the practice room so we thought a lot about why we had to go around outdoors shaking during the winter."�Soyul also remembered the tears she spilled at the time, sharing,�"Because there were many who didn't recognize us, we were a bit sad as we would hold up signs that read, 'We are singers. We're a girl group. We're Crayon Pop. We will take photos with you.' That is why I cried with my unnis before holding up the signs."

Their agency CEO revealed how sorry and determined he felt for the girls, sharing, "I felt really sorry to their parents for making their children perform guerrilla concerts on really cold days and seeing them shivering in the cold on the street. I thought to myself that I have to help them succeed no matter what."
