UEE revealed how idols secretly exchanged numbers at SBS' 'Inkigayo.'

On the April 11 airing of tvN's' 'Life Bar,' UEE shared, "There's a vending machine in front of the waiting rooms at 'Inkigayo'. I heard they used to tape their numbers behind the vending machine, or buy a drink and tape their numbers on the bottom of the cans and exchange it that way. I was looking forward to that when I promoted as a singer but it never happened to me."

MC Heechul commented, "I know that vending machine too," but, "I've never done it myself."
