Hyojung of OH MY GIRL Wrote Everything on 'Purple Note'

OH MY GIRL's main vocalist Hyojung is returning with her most personal solo work to date. The singer will release her digital single "Purple Note" on May 21, 2026 at 6 PM KST — a project that draws directly from her own memory, named after the vocal club she was part of during high school. Every song on the single was written and composed by Hyojung herself, making Purple Note less a standard solo comeback and more a handwritten record of who she was before the world knew her name.

The announcement, accompanied by a series of posters that contrast teenage Hyojung with the artist she has become, has generated a warm and distinctly emotional response from fans. There is something about watching someone process their own story through music — especially someone whose voice has been a constant in their listening life — that hits differently from a typical comeback. Purple Note seems designed to create exactly that feeling.

Where the Name Comes From

The title Purple Note isn't a stylistic choice. It's the name of the vocal club Hyojung sang in as a high school student — a place where she first seriously pursued music before any of the auditions, the training, or the cameras. By naming her solo single after that club, Hyojung is doing something that artists rarely manage to pull off without it feeling like a marketing move: she's tracing a thread between who she was then and who she is now, and finding it still intact.

The concept carries through to the project's promotional materials. Two visual samplers released in the lead-up to the single's drop follow a teenager named Choi Hyojung — the singer's birth name — as she chases a dream, set alongside the present-day Hyojung who has lived that dream out. The tagline accompanying the campaign reads: "We were each other's youth in those brilliant days." It's the kind of framing that works only when the story underneath it is real, and everything about Purple Note suggests it is.

What's on the Single

Purple Note is a compact release: a title track, a B-side, and an instrumental version of the title. The title track "나의 작은 청춘에게" (To My Small Youth) is the emotional center of the project. Written and composed entirely by Hyojung, it's framed as a message to her younger self — the kind of letter that can only be written from the far side of the journey, when you finally understand what all those early, uncertain steps were building toward.

The B-side, "Look Around", rounds out the release with a complementary perspective. Where the title track looks backward with tenderness and gratitude, "Look Around" is, by implication, an invitation to be present — to pause on the path rather than always chasing the horizon. Together, the two tracks create a small but coherent emotional arc, the kind you don't get from albums assembled from disparate writing sessions.

What makes Purple Note particularly notable in the context of Hyojung's career is the degree of creative ownership she has taken here. Writing and composing everything on a solo project is a meaningful act of artistic declaration — a signal that what you're hearing is not interpreted material but direct expression. For a singer who has spent years as OH MY GIRL's main vocal, a role defined by serving songs someone else wrote, the autonomy of Purple Note is a statement in itself.

Hyojung's Place in K-Pop's Vocal Landscape

OH MY GIRL debuted in 2015 under WM Entertainment and has spent the decade since establishing one of K-pop's most distinctive group identities — warm, fantasy-tinged, emotionally sincere, built around harmonies that showcase the group's vocal depth. Within that group, Hyojung has consistently anchored the sound as main vocalist, the one whose tone sets the emotional temperature of any song she leads.

Her solo work has come in measured intervals. This release follows the special single "크리스마스 야간열차" (Christmas Night Train), released in December 2024 — a roughly one year and five month gap that kept the interest in her solo material alive without overexposing it. That kind of pacing reflects confidence: the knowledge that an audience will wait if the music is worth it.

Purple Note is her first fully self-penned solo project, which places it in a different category than previous releases. This isn't a singer interpreting material handed to her — it's an artist assembling a record from her own experience and presenting it to listeners to do with what they will. The vulnerability of that act is part of what makes the early fan response to Purple Note's promotional rollout so warm. People can feel the difference.

What Fans and the Industry Are Watching

The lead-up to Purple Note's release has been notable for how deliberately understated it is. Rather than large-scale performances or complex reveal events, Hyojung and her label have leaned into intimate visual storytelling: the school uniform, the MP3 player, the handwritten notes on a purple staff sheet. It's a rollout that trusts the audience to slow down and pay attention, rather than demanding it through spectacle.

That approach aligns with what the music itself seems to promise: something built to be listened to closely, revisited, and felt rather than consumed and moved past. In an era when K-pop releases can feel engineered for maximum initial impact and minimum shelf life, Purple Note signals a different set of intentions. Hyojung appears to be making something she wants to still be singing years from now.

The single drops on May 21, 2026. Fans who have followed OH MY GIRL through their decade of work — and particularly those who have watched Hyojung grow from a teenager auditioning with a dream into one of K-pop's most trusted vocalists — are unlikely to approach this release casually. Purple Note is the kind of project that rewards the people who have been paying attention all along, which is exactly the audience Hyojung has earned.
