NMIXX officially debuted on February 22, 2022, at 6 pm after releasing its first single "AD MARE" and title track "O.O"

The debut song "O.O" has an unusual atmosphere from the name of the song, drawing attention from K-pop fans. It symbolizes the appearance of wide-open eyes in surprise and the exclamation "Oh!," expressing strong confidence that you will be surprised to see something new. By combining two or more genres into one song, the "MIXX POP" genre, which allows you to feel various charms at the same time, was introduced and imprinted on NMIXX's unique music color.

As proof of this, the "O.O" music video surpassed 1 million YouTube views in about two hours after its release and exceeded 4.7 million views as of 9 am on February 23rd. In particular, at 1 am on the 23rd, seven hours after its release, it topped YouTube Trending Worldwide and proved its keen interest. Thanks to a flurry of requests, the light version of the debut single "AD MARE" topped the retail album real-time chart on Gaon Chart on the afternoon of February 22nd, the day of its release, adding fire to the enthusiasm of the debut single "Blind Package."
