JTBC’s “MIXNINE” has released another preview of its upcoming episode, giving viewers a peek at the battle for the center position.

In the clip, tensions are high as male and female trainees prepare for the position battle performances. The instructor watching the male trainees frustratingly comments, “What are you doing? I don’t know what you’re telling me to see.”

The situation isn’t all that different for the female contestants, where they are also getting told by their instructor that they are too weak and not doing enough to beat the boys.

Then, the contestants practice harder and voice their determination as they practice to perfect their performances. Viewers can see small bits of the contestants performing popular songs such as Song Mino’s “Okey Dokey” and 2PM’s “My House.” After the performances, the contestants anxiously wait for the results and show shock once they’re announced.

This episode of “MIXNINE” will be an extended episode by 50 minutes showcasing all position battle performances, and will air on Sunday, December 3 at 4 p.m. KST.

Watch the nerve-wracking preview below!
