On July 21, 2026, a teaser titled "2026 Summer of NewJeans: HAERIN" was published on YouTube, crediting Nayeon Kim as Creative Director with Dana Kim and Yewon Yang handling Creative Direction & Arrangement. The launch coincided with NewJeans' fourth anniversary on July 22, prompting widespread comeback speculation among fans (Korea Herald).

Five videos were released under the "2026 Summer of NewJeans" banner: one group teaser and individual teasers for each of the four featured members — Minji, Hanni, Haerin, and Hyein. Danielle Marsh was absent from the campaign (Rolling Stone Philippines). The campaign marks NewJeans' first teaser release since 2024.

Ador, however, has pushed back on the narrative the teasers imply. The agency stated that nothing has been decided regarding a NewJeans comeback as of July 22, 2026 (Korea Herald). The gap between the creative output — coordinated, branded, and disseminated across official channels — and the agency's public posture is notable, particularly given the legal and corporate disputes surrounding the group.

The teasers' release comes amid ongoing litigation between Ador and former CEO Min Hee-jin. During a third court hearing, Ador submitted new evidence alleging that Min orchestrated NewJeans' effort to leave the agency. A Seoul court had already approved Ador's request in February 2026 to freeze assets belonging to Danielle's mother and to Min Hee-jin (Korea Herald). Rolling Stone Philippines framed its coverage explicitly around Danielle's exclusion, titling its report "NewJeans Finally Comes Back Minus Danielle Marsh."

The broader context here is one of fractured control. The group's commercial momentum has not entirely stalled in the interim: NewJeans' song "Right Now" surpassed 100 million streams as reported on July 13, 2026 (Korea Herald). But the question of who controls the NewJeans brand and creative direction — the members, Ador, or external creative teams — remains contested, and the teaser campaign's execution with only four members visually codifies the group's current configuration regardless of the agency's official stance.

What remains unresolved is whether the "2026 Summer of NewJeans" teasers presage a formal comeback with new music or function as anniversary content designed to maintain visibility during a protracted dispute. Ador's statement that nothing is decided leaves the campaign in an ambiguous position: the creative work has been done and distributed, but the commercial pipeline it would normally initiate has not been confirmed. For an industry that relies on tightly choreographed rollout schedules, that ambiguity is itself the signal.
