ONF (온앤오프)

ONF made history before their comeback album even dropped. The seven-member group under WM Entertainment became the first idol group in the Korean entertainment industry to enlist for mandatory military service together as a unit — a collective decision that effectively paused their career and, upon their return, redefined their identity. Their 2026 second full-length album *ONF: MY SELF* marks not just a post-military reentry but a full agency transition, situating the group at one of the more consequential turning points of their near-decade run.

Debut and Formation

ONF debuted on August 2, 2017, under WM Entertainment, releasing the self-titled EP *On/Off* to introduce a group concept built around duality — the name itself signaling a tension between opposing states. The group, whose Korean name is 온앤오프, attracted a dedicated fandom known as FUSE from early in its career. Working across dance-pop, hip-hop, and broader K-pop frameworks, the group positioned itself through sharp choreography and a layered sonic identity that set it apart from the more straightforward idol fare of its label peers at the time.

Members

ONF operates as a seven-member group. The current lineup consists of E-Tion (lead vocalist), Hyojin, Laun, Minkyun (formerly credited as MK), Seungjun (formerly credited as J-US), Wyatt, and Yuto (formerly credited as U). The name adjustments for Minkyun, Seungjun, and Yuto reflect a rebranding that accompanied the group's evolution across different release cycles.

Music and Discography

The group's discography traces a steady expansion in scope. Following their 2017 debut EP *On/Off*, they released *You Complete Me* in 2018, deepening the melodic and emotional range of their output. The 2019 releases — *We Must Love* and *Go Live* — marked a particularly productive stretch, demonstrating a capacity for both warmth and high-energy production within a single calendar year. *Go Live* in particular helped consolidate the group's artistic footing heading into the 2020s.

The 2021 EP *Popping* arrived during a period of broader industry disruption and carried a lighter, more vibrant tone, signaling the group's willingness to shift registers between projects. It remains among their more commercially visible releases.

Their 2026 return, the second full-length album Part.2 *ONF: MY SELF*, was preceded by concept photo sets organized across four visual themes — "LOST," "FACE," and "STEP" among them — and a highlight medley video previewing six tracks including the title song "Open The Door." The music video teaser for "Open The Door" leaned into a narrative-driven tension, framing the comeback as a continuation of the group's storytelling approach rather than a reset.

A Collective Enlistment and Agency Move

ONF's decision to enlist for military service as a complete group unit was without precedent in the idol industry. Rather than staggering enlistments — the standard approach, designed to maintain a group's public presence across the enlistment period — ONF chose to go together, accepting a full operational pause in exchange for returning intact. The move was widely noted within the Korean entertainment industry as a logistical and symbolic statement about group cohesion.

Their return was accompanied by a change of agency, adding an additional layer of transition to what was already a significant reentry. The fan meeting *Re:Connect*, held ahead of the June 2026 album release, served as the initial point of contact between the group and their audience after the enlistment period, and it was there that the June comeback was formally announced.

Standing

ONF enters their post-enlistment chapter with a discography that spans nearly a decade and a fan base that followed them through an unusually long collective absence. The circumstances of their return — unprecedented group enlistment, agency transition, and a new full-length album framed through an explicit self-narrative — give *ONF: MY SELF* a weight beyond most comeback releases. Whether the record expands their reach beyond the FUSE fandom remains to be seen, but the structural decisions ONF made as a group have already distinguished them within the mechanics of the idol industry.
