Boy group NEXZ(Nexz), under JYP Entertainment, announced their comeback by releasing their second single album 'Mmchk' and its title track on April 27 at 6 PM. Ahead of the comeback, on the 17th at noon, they revealed a highlight medley video on their official SNS channels, showcasing some of the new album's tracks for the first time.

The released video shows Tomoya, Yuu, Haru, So Gun, Seita, Huey, and Yuki focusing on dance practice with a cassette player nearby. The members practiced seriously, synchronizing their movements, and the video also captured moments of them catching their breath and smiling brightly. When Yuu made a presence by making a noise during the video, the members gathered and started the performance of the title track 'Mmchk.'

The performance of 'Mmchk,' which includes the lyrics "Not typical," features an addictive beat and cheerful rap, showing a different charm from before. The second track, 'HYPEMAN,' written solely by Tomoya and Yuki with lyrics like "All night long You and I play together With this music," stood out with catchy choreography that matched the music.

Various dance teams and choreographers such as We Dem Boyz, NAIN&CHAEWON, Y NOT, and The BIPS participated in the album's performances. Through NEXZ's signature teasing content, the performance highlight medley, they emphasized their capabilities as a 'group of all dance talents.'

Last year, they advanced to the finals in the random play dance on the tvN variety show 'Business Trip Fifteen Nights X JYP Scout' and were recognized for their skills by famous dancers like Bada and Waxxi.
