[OSENWORLD] NMIXX have officially claimed the season’s crown. The girl group’s latest single Blue Valentine has climbed to No.1 on Melon’s Top 100 chart, ending the long-standing reign of Golden, the breakout OST from Netflix’s global animated hit K-Pop Demon Hunters.
Released on October 13 as the title track of their first full-length album, Blue Valentine soared to No.1 just a week later — only 23 hours after first reaching No.2 — marking a new career high for the six-member act.
The single debuted at No.85 on Melon’s daily chart and has since climbed steadily, breaking into the Top 10 by October 19. It also claimed No.1 on Bugs’ daily chart and No.2 on its weekly ranking (Oct. 13–19), while the full album debuted atop Hanteo’s weekly album chart during the same period.

NMIXX’s first studio album Blue Valentine captures the inevitable conflicts and dual emotions that come with love, blending autumn’s wistful mood with a soaring chorus that listeners have dubbed a “fall carol.” The song’s emotional pull, paired with the members’ harmonious vocals, has resonated deeply with fans.
Following its release, NMIXX performed Blue Valentine and SPINNIN’ ON IT across major Korean music shows, including M Countdown, Music Bank, Show! Music Core, and Inkigayo. Their flawless live vocals and razor-sharp synchronization earned widespread praise, reaffirming their reputation as K-pop’s “hexagonal group” — a team known for balance across vocals, dance, visuals, and stage command.
Fans have filled social media with glowing reactions, saying: “This song and performance deserve more love,” and “I can’t stop watching their stage videos.”
Riding the momentum, NMIXX will kick off their first-ever world tour EPISODE 1: ZERO FRONTIER at Inspire Arena in Incheon on November 29–30, marking a defining step in NMIXX’s rise as a next-generation global powerhouse.
