NMIXX began rolling out teasers for their August comeback.

On August 2 at midnight KST, the group released the first teaser, beginning their official preparation for their comeback. The latest story film teaser provides an interesting narrative, "A break in the wall, yet my true identity still escapes to stick out. Fear resists me from daring to step outside. I want to shine, but the dark defends me well. Either deep underground or under my bed, lies the side of me that people hate because no one likes the black sheep. I'm fed up, annoyed, thirsty, and lonely. How much longer will I stay in here? Let me leave now. Somebody get me out of here."

The trailer also opens up with Sullyoon stuck on a stranded island as she finds ways to escape.

Meanwhile, NMIXX will be making a comeback on August 19 at 6 PM with 'Fe3O4: STICK OUT,' so stay tuned for more teasers until then!
