What I like about them, Dreamcatcher girls always know when to be chaotic & when to behave decently. As chaotic they are, they never went overboard. There's is one time when SuA, JiU & Yoohyeon got invitation from another agency to teach & guide their junior idol trainees, probably age around 12-13 years old. They all seems pretty calm & well behave in front of them (young idols). Probably they don't want to show their chaotic nature in front of other young idols. They know that adult should show good example to the young ones. Good attitude comes first, crackheads later...:P

The clip from the show you were asking about is from Dreamcatcher - Idol Live School 3 (221019)

That radio DJ whose voice you recognized is Kim Shin Young. She was a host on Weekly Idol for a brief period (part of a trio). She has been hosting her "Noon Song of Hope" radio show for almost a decade now, along with co-/hosting several TV shows. She's known as a "super insider" with tons of idol friends and very few, if any, scandals or rumors.

There’s no controlling their chaos
