Nexz announced their comeback on the 27th by releasing a trailer for their new album 'Mmchk' through their official SNS channels. The trailer video features the seven members showcasing their individual personalities: Haru building a card castle, Huey reading a book, So Geon observing jelly, Seita repeatedly tossing and catching chalk in the air, Yuki turning a stand light on and off, Tomoya deep in thought, and Yuu petting a cat.

On the TV in the video, a public service announcement about dining etiquette is playing, followed by a scene where a neatly dressed person explains proper posture, quiet eating, and dignified manners. When Yuu makes a noise, the members' attention is drawn, causing the card castle to collapse and the chalk to break in two. The black cat that was in Yuu's arms also leaves, noise appears on the screen, and the album title 'Mmchk' emerges through the static.

This new album is the first release in about six months since the mini-album 'Beatboxer' released last October. Nexz is set to begin their first activities in the music industry in 2026. The seven-member boy group Nexz is recognized as JYP's global rising star, known for their performance skills and diverse charms.
