Super Junior’s Leeteuk and Heechul Set July 13 Debut for New Unit SUPER JUNIOR-83z

Super Junior members Leeteuk and Heechul are turning one of K-pop’s longest-running friendships into an official unit project. SM Entertainment’s veteran group will add a new subunit, SUPER JUNIOR-83z, with the duo scheduled to make its formal debut on July 13.

The unit brings together the two 1983-born members who have long been recognized as part of Super Junior’s eldest line. According to reports citing SM Entertainment, SUPER JUNIOR-83z will release its first mini-album, Promise, on July 13, with pre-orders beginning July 1 through online and offline music retailers.

The timing gives the project a commemorative feel. Super Junior debuted in 2005 and has remained active across music, variety, acting, touring, and solo work for more than two decades. A dedicated unit built around Leeteuk and Heechul places the focus on two members whose public images have often balanced performance, broadcasting, and team leadership.

A Six-Track Mini-Album Built Around ‘Promise’

The first mini-album will contain six tracks, led by the title song “Promise”. The set will also include “ONSAEMIRO,” a song the pair previously performed during Super Junior’s 20th-anniversary world tour encore concert in April.

That connection is important because it frames the album as more than a one-off collaboration. Rather than introducing the duo through an entirely separate concept, the release draws from the broader Super Junior anniversary cycle and gives fans a recorded version of material already tied to a major milestone in the group’s career.

SM Entertainment has positioned the pairing around the members’ shared age and long history within the same team. The name SUPER JUNIOR-83z directly references their birth year, while the Korean rendering has also been promoted as “Pal-samz,” a shorthand that underlines the same 1983 identity.

For newer K-pop audiences, subunits are now a standard part of idol group strategy. For Super Junior, however, they have been central to the group’s identity for years, allowing different members to explore ballads, trot, Mandopop, dance music, and performance-focused formats. SUPER JUNIOR-83z continues that tradition with a pairing built less around novelty than around familiarity.

Fan-Con Tour To Follow The Album

After the album release, Leeteuk and Heechul are expected to begin their first fan-con tour, titled “1983.” Earlier announcements listed Seoul as the opening city on July 25, followed by stops in Tokyo, Bangkok, Hong Kong, Kuala Lumpur, Macau, Kaohsiung, Singapore, and Taipei.

The tour plan suggests that the unit is being treated as a full promotional project rather than a limited digital release. Fan-con events typically combine live performances, talk segments, games, and fan interaction, making them especially suitable for artists whose appeal includes both music and variety-show personalities.

Leeteuk, Super Junior’s leader, has built a public profile as an MC and broadcaster while continuing to anchor the group’s stage activities. Heechul has likewise maintained a broad entertainment presence, known for television work and an outspoken personality that has kept him visible beyond traditional idol promotions.

Those parallel careers give SUPER JUNIOR-83z a clear hook: the unit can lean on two performers who are already familiar to Korean and international audiences in multiple formats. The question now is how the music and stage direction will balance nostalgia with a distinct unit identity.

The July 13 release also arrives during a crowded summer period for K-pop, when established acts and newer groups are competing for attention through albums, festivals, and tour announcements. A Super Junior unit carries a different kind of weight in that calendar: it speaks to longevity, fandom continuity, and the industry’s growing interest in keeping veteran acts active through flexible formats.

For fans, Promise will be the first real test of what Leeteuk and Heechul sound and look like when presented as the central duo rather than as part of Super Junior’s larger lineup. With a six-track album and an Asia fan-con schedule already attached, SUPER JUNIOR-83z is entering as a complete project with room to define its own lane.
