Mnet's 'Lan Cable Friends IOI' aired on July 8!
On this day, Kim Do Yeon was asked to tell a secret about her best friend Choi Yoo Jung, and she said, "These days, Choi Yoo Jung doesn't wash up and she just goes to bed."
Taken aback, Choi Yoo Jung explained, "That's not true. It's not that I don't wash up but that I can't wash up. I fall asleep while waiting [for my turn to use the bathroom]." Kim Do Yeon fired back by saying they didn't have a set or specific order for who uses the bathroom first.
