NMIXX will release their first full-length album, "Blue Valentine," on October 13th. This marks NMIXX's first full-length album since their debut in February 2022.

NMIXX concluded their "Fe3O4" series with their fourth mini-album, "Fe3O4: FORWARD," released in March, which explored the story of a group forced to remain in the real world known as "FIELD."

The first teaser motion poster for "Blue Valentine" has piqued curiosity about the new story NMIXX will unfold.
