Popular South Korean boy group EXO is gearing up to debut a brand new subunit. Members Kim Kai (김카이) and Oh Se-hun (오세훈) have been confirmed to form the new duo, with an official debut expected in December. Both born in 1994, the two are affectionately known as the “94 Line” among fans. They have previously garnered significant popularity for their outstanding visuals, impressive physiques, and powerful stage presence. Now, their official collaboration as a subunit has been announced, immediately sparking enthusiastic discussion among fans.
According to a November 2 report by Korean media outlet NewsEn, Kai and Sehun will officially debut as a subunit in December. Not only are they same-aged members within the group, but they have also consistently been a highly favored pairing by fans. With their first-ever subunit activities, there is considerable anticipation for the new synergy they will create, distinct from their group performances.

In fact, Kai and Sehun's collaborative chemistry has long been recognized by fans. Last year, when Kai held his solo concert, Sehun made a surprise appearance as a guest, performing together on stage to the delight of fans. In January, Sehun also appeared on the spin-off program “All-Round Date” from the online variety show “All-Round Student,” hosted by Kai, for its winter break special. Their playful banter and teasing interactions on the show showcased their natural and amusing close friendship off-stage.
Furthermore, the two also appeared together as travel partners on the ENA and TEO collaborative variety show “Global Rotation World Travel 4,” revealing a different side of themselves away from the stage, which garnered significant affection from viewers. It is reported that after their official subunit debut, in addition to music and stage activities, they also plan to meet fans through various variety shows and different forms of content, generating considerable excitement among their fanbase.

As news of Kai and Sehun's upcoming subunit debut broke, it quickly trended on Korean online forums, sparking heated discussions among netizens. Many excitedly commented, “It's finally happening!”, “This is insane,” “This is great, I hope it's a very mature and sexy concept,” “I didn't expect this combination,” “Daebak!”, “I'm going crazy,” and “Completely looking forward to it!”, expressing immense anticipation for their new collaboration.
Meanwhile, EXO celebrated their 14th debut anniversary this year and released their 8th full-length album, “REVERXE,” in January. The album not only marked the group's 8th million-selling album since their debut but also topped domestic and international album and digital music charts, securing five wins on music programs, demonstrating impressive achievements.
Additionally, EXO held a three-day concert series from April 10 to 12 at KSPO Dome in Olympic Park, Songpa-gu, Seoul, which served as the starting point for their world tour. The tour successfully concluded after 27 performances across 14 regions worldwide. Now, with the news of Kai and Sehun's new subunit, fans are even more excited for EXO's upcoming activities.
