The ten girls come to 825 Entertainment, ready to become idols.
But Shinhyuk announces something unexpected. They will be going through a “mock test” of sorts, and the girls have just one week to prepare!
They only met yesterday; how are they supposed to become a team? Thrown off balance, the girls direct all their energy into practice.
But this is Suji’s first time dancing, and she keeps messing up. To make matters worse, the girls start fighting from the get-go.
The original five insist on sticking to their way of practicing, but the new girls are not having any of it.
Reaching their boiling point, in the end, they decide to practice separately.
