Jaehyun, a member of the group NCT, has released a new solo single and accompanying music video titled "99 Degrees" [1, 2].

The release marks a strategic pivot for the artist, who said the project was a gift to his fans and a way to showcase a new artistic direction [1]. By stepping away from the collective group sound, Jaehyun is establishing a distinct solo identity within the global music market.

Promotion for the project began earlier this month. A teaser for the release was posted July 3, 2026, at 12 a.m. KST [1]. The teaser served as the initial introduction to the visual and sonic palette of the new single before its full debut.

The music video was posted via the SMTOWN YouTube channel, and the song is available across major streaming platforms [1, 2]. The rollout follows a pattern of high-production visual storytelling common in the South Korean music industry, focusing on a blend of choreography and cinematic aesthetics.

While the project is a solo effort, it remains tied to the broader ecosystem of NCT. The transition from group member to solo artist allows for more experimental songwriting and production choices that may not fit the standard group format [1].

“Jaehyun released the song as a gift to fans”

This solo venture reflects a growing trend among K-pop idols to diversify their portfolios and build individual brands. By launching '99 Degrees,' Jaehyun is testing his viability as a standalone performer, which can increase his leverage for future contracts and artistic collaborations outside the traditional group structure.
