Nexz(NEXZ) is preparing for their comeback by releasing various promotional content ahead of the release of their second single, 'Mmchk.'

On the 20th, Nexz pre-released the challenge section of the title track 'Mmchk,' featuring members Tomoya and Yuu. Then, on the afternoon of the 21st, a group dance challenge video with all seven members was released, attracting fans' attention. The members showcased perfect synchronized choreography to an exciting rhythm, demonstrating performances worthy of the nickname "the group of dance prodigies." Their outstanding dance skills have also been confirmed through their own performance project 'NEXZ Archive(Nexz Archive)' and the random play dance corner on tvN variety show 'Business Trip Fifteen Nights X JYP Scout.'

The highlight medley video released on the 17th also captured Nexz's unique performance charm and is approaching 1 million views on YouTube as of the afternoon of the 21st. The pre-released choreography challenge video is stimulating the challenge spirit of K-pop fans.

This single 'Mmchk' includes a total of three tracks: the title track of the same name, 'HYPEMAN,' and 'Mmchk (English Version)' for global fans. Yuki, Huey, and Tomoya participated in writing the lyrics for the title track, while 'HYPEMAN' was solely written by Yuki and Tomoya.

Nexz's second single 'Mmchk' will be released worldwide on all music platforms at 6 PM on the 27th. On the same day at 8 PM, a comeback showcase titled 'Mmchk' will be held. Afterwards, Nexz plans to appear on various domestic and international stages, including a global showcase event, their first arena tour, and Brazil's music festival 'Rock in Rio.'
