The Seoul-based artist captures the quiet tension of falling for a close friend in a playful yet emotionally layered track.

Seoul-based singer-songwriter iiso has released her new single “Best Friend,” marking a notable collaboration with global producer Mura Masa.

Released on May 29, iiso Best Friend captures the complicated feeling of having a crush on a close friend. On the surface, the track feels bright, playful, and charming, but beneath its catchy hook lies the anxiety and emotional uncertainty of unrequited love.

Produced by Mura Masa, the song highlights the UK-inspired sonic direction that iiso has been exploring in her recent work. Its playful melodies are paired with hard-hitting drum sounds, creating a contrast that mirrors the emotional push and pull at the heart of the song.

The track’s dreamy atmosphere is further shaped by mixing from Humming Urban Stereo, also known as HUS, whose multidimensional sound adds depth to the final production.

The music video reunites iiso with director Lafic, who previously worked with her on “Salad Days.” Through refined visuals and a distinct creative tone, the video expands the world of iiso Best Friend while reinforcing her unique artistic identity.

As an artist, iiso continues to build a creative universe where music, fashion, and visual art work together as one language.

Known for dreamy vocals, polished melodies, and a modern interpretation of Y2K and alternative influences, she has emerged as one of the next-generation Korean solo artists to watch.

Beyond singing and songwriting, iiso also takes part in producing her releases and directing the visuals, styling, and artwork around her projects.

Positioned between the Korean underground scene and global internet culture, iiso continues to blur creative boundaries with every release.

“Best Friend” shows iiso’s ability to turn a familiar emotional experience into a polished, globally minded pop moment filled with charm, tension, and individuality.
