In what many fans are calling the most shocking comeback of the year, NMIXX has made an unprecedented leap to the top of Korea’s music charts. On October 13, the JYP girl group officially released their long-awaited first full album, Blue Valentine, led by the title track of the same name a dreamy synth-pop number that has quickly become a sensation.

The Blue Valentine MV surpassed 30 million views within eight days, a milestone signaling not just NMIXX’s revival but also a rare surge for a girl group in a market facing stagnation.

Initially, expectations were low. The single debuted at #107 on Genie and #73 on Melon, a typical performance for NMIXX often labeled JYP’s “most unlucky” group. Yet, against all odds, Blue Valentine began climbing relentlessly.

Within days, it cracked the Top 20, then Top 10, before ultimately reaching #1 on both Bugs and Melon on October 20 marking the group’s first-ever digital chart No. 1.

The song’s success didn’t just bring NMIXX a long-awaited breakthrough it ended the 100-day reign (2,388 hours) of Golden, the record-breaking virtual group hit by HUNTR/X, known as the longest-running K-pop chart-topper in history.

Social media exploded with reactions as NMIXX dethroned Golden. Fans praised the group’s resilience and artistry, declaring the achievement a “miracle” comeback that no one saw coming.

“From rank 107 to #1 in a week this is the Cinderella story of K-pop,” one viral tweet read.

Even Blue Valentine’s initial album sales astonished industry watchers nearly 500,000 copies sold in just one day, NMIXX’s highest first-day total to date.

The MV earned acclaim for its cinematic artistry. Using cool blue and silver tones with glimmers of gold, it blurs the line between dream and reality. Each frame resembles a surreal painting, while the choreography emphasizes fluidity and elegance.

Musically, Blue Valentine marks a turning point for NMIXX. Known for their experimental “mix-pop” sound, the group this time strikes a delicate balance between innovation and melody. The song’s airy synth lines and emotional chorus evoke nostalgic anime-like magic instantly catchy yet deeply emotional.

As of now, Blue Valentine continues to swap positions with Golden atop Melon’s real-time chart. Analysts predict that the track could soon earn NMIXX’s first “RAK” (Real-Time All-Kill) as radio play and music-show promotions ramp up.

Once dismissed as JYP’s “forgotten daughters,” the six members of NMIXX have rewritten their narrative proving that perseverance, artistry, and timing can turn even the most unlikely story into K-pop history.
