On September 8, 2025, EXO surprised fans by dropping a mysterious teaser image on their official social media at 1:26 AM. The teaser confirmed that the group is preparing for a comeback in December 2025.
The post included the phrase “WHEN WE BECOME TRUE ONE, A NEW WORLD AWAKENS”, instantly sparking excitement among EXO-Ls worldwide.
The timing of the release made it even more special. The teaser dropped during a lunar eclipse, connecting once again to EXO’s signature cosmic storyline. Fans quickly pointed out the significance, saying it felt like “the universe aligning with EXO’s return.”
Sehun’s Discharge from Military Service
Adding to the excitement, EXO’s youngest member Sehun will be discharged from his alternative military service on September 20, 2025. His return completes an important chapter for the group, as all members will finally be available for activities together. Fans have been counting down the days, with many sharing posts like:
We’ve waited so long for Sehun — now EXO is truly complete.
This milestone makes the December comeback even more emotional, as it sets the stage for the long-awaited OT9 reunion.
What Fans Can Expect from the Comeback
The comeback teaser’s powerful message has fueled speculation about what EXO will bring this time. Many believe the phrase hints at a new era of EXO’s storytelling, blending their cosmic mythology with a fresh sound and concept.
Since their debut in 2012, EXO has been known for groundbreaking concepts and high-quality performances. Their last album release as a group was Don’t Fight the Feeling in 2021, which already feels like a lifetime ago for fans.
With over four years since their last full album, the December 2025 comeback is expected to be one of their most emotional and impactful returns yet.
Fan Reactions Around the World
The announcement immediately trended across platforms like Twitter, Weibo, and community forums. Fans shared emotional reactions such as:
I was crying the moment I saw the teaser. An OT9 comeback feels like a dream.
The lunar eclipse teaser gave me chills. EXO always knows how to make it magical.
With Sehun back, this is the comeback we’ve all been waiting for.
Many fans also expressed hopes for a full-length album and a world tour, saying this moment deserves to be celebrated on the biggest stage possible.
Why This Comeback Matters
EXO’s return is not just another release; it’s a historic moment in K-pop. Few groups have stayed together through more than a decade of ups and downs, military service, and solo careers, only to reunite with all members.
For EXO-Ls, the December comeback is more than music; it’s proof of the group’s bond and resilience.
The Countdown Begins!
As the countdown to December begins, EXO-Ls are celebrating more than just a teaser. They are preparing to witness the long-awaited return of their nine shining stars.
