NMIXX has reached a new milestone in their career with their latest release.

The group dropped their first full-length album Blue Valentine on October 13, featuring 12 tracks including the title song of the same name. The track quickly climbed domestic streaming charts, reaching No.2 on Melon's Top 100 as of midnight on October 20 — the group's highest chart position to date.

Their previous peak was No.4 with Love Me Like This, making Blue Valentine a major leap forward in NMIXX's discography. The song also entered Melon's Daily Chart at No.10, rising more than 70 spots in just one week, while maintaining the No.1 position on the Hot 100.

Through the new album, NMIXX expressed their ambition to make listeners wonder, "How far can they go?" The achievement reflects their steady rise and growing momentum in the K-pop scene.

NMIXX will hold their first world tour, Episode 1: Zero Frontier, at Inspire Arena in Incheon on November 29–30.
