EXO’s Kai and Sehun are preparing to debut as a duo this December, bringing together two members whose individual styles have made them recognisable names in K-pop and fashion.
According to a November 2 report by Newsen, the pair are set to officially debut as a new subunit next month. While their musical direction, concept and release date have yet to be announced, the news has already drawn attention to what the two performers could bring to the stage together.
Both born in 1994, Kai and Sehun have long been known among fans as the “94z.” Another familiar nickname is “SEKAI,” a combination of their names that fans have used over the years.
The two have performed together throughout their careers with EXO, but their upcoming debut will give them an opportunity to explore music specifically as a duo. Sehun previously made a surprise appearance during Kai’s solo concert, while their appearance on Jeongwaja highlighted their friendship and playful chemistry outside the stage.
Two Different Styles, One Subunit

Kai has established himself through his solo music, expressive choreography and fashion. His approach to performance often places equal attention on movement, music and visual presentation, with styling playing an important role in his artistic identity.
Sehun, meanwhile, is recognised for his sharp dance movements, understated personal style and presence onstage. His previous promotions alongside Chanyeol as EXO-SC have also given him experience performing in a smaller unit outside EXO’s full-group activities.
While their individual styles differ, both have spent years developing their identities as performers. Their upcoming debut will offer a chance to see how those strengths work together through music, choreography and visual concepts created specifically for them.
For fashion audiences, the styling and concept photography will be particularly interesting to watch as they both have a strong fashion sense. Both members have established a presence beyond music, and their first official release together could introduce a visual direction different from their previous projects.
What Can We Expect From Kai and Sehun?

Performance will likely be one of the biggest points of interest surrounding their debut. With both members known for their dancing, fans will be looking forward to seeing the choreography and stage performances prepared for the duo.
Their musical direction remains unknown. Kai’s solo releases have explored different sounds and concepts, while Sehun’s work with EXO-SC has shown another side of his musical style.
Beyond music, the pair are also scheduled to appear together on World Dice Tour 4, giving fans another opportunity to see their chemistry outside performances.
Although their December debut has been reported, the official subunit name, concept, album details and promotional schedule have yet to be revealed.
For now, attention turns to their first concept photos and music previews, and how Kai and Sehun will present themselves as a duo after years of performing together as EXO members.
