NMIXX heated up their comeback with fresh promotions.

On the 29th, NMIXX released the promotional video for their 3rd mini album 'Fe3O4: STICK OUT'. The unknown atmosphere raised expectations for the new album concept.

In the image, a mysterious ARS number appears on the screen that shakes as if there is an error. When you call that number, a message saying, "The girls are waiting for your call" flows out.

The messages the six members deliver are also meaningful. Haewon is hiding and looking for a way out of a lost place, and Gyujin introduces the black sheep ghost story of the 3rd floor bathroom at school.

Jiwoo moves to pick up a friend who keeps hearing strange sounds. Seol-yoon experiences the same repetitive daily life as if she is trapped somewhere. It stimulates curiosity about what will happen to the members.

NMIXX recently successfully completed the 8th performance as part of their first fan concert since their debut, 'NMIXX Change Up: Mix University'. They visited Seoul, Hong Kong, Taipei, and Macau.

They also expanded their global presence. They performed at 'I Days' in Milan, Italy and 'British Summer Time Hyde Park' in London, England. They showed their presence as an all-rounder group.

Meanwhile, NMIXX will release their 3rd mini album 'F3Rio4: Stick Out' on various music streaming sites at 6 PM on the 19th of next month. This is their first comeback in about 7 months.

They are also preparing for their 2nd fan concert. NMIXX will be holding 'NMIXX Change Up: Mix Lab' from October 4th to 6th at Jangchung Gymnasium in Jung-gu, Seoul.
