Group EXO revealed that they appeared on a radio program on a first come, first serve basis.

On SBS PowerFM "Kim Chang Ryeol's Old School" aired on Monday, DJ Kim asked EXO, "How come only three of you came today?" and Suho answered, "The three members who wanted to come the most came on a first come, first serve basis. Some members had other schedules and there's too many of us to come anyway."

Chanyeol also added, "Sometimes some members just come and sit and leave," arousing laughter.

On this day, members Suho, Chanyeol, and Kai appeared as guests.
