A surprise photo appeared on EXO's official Instagram account.

A few days ago, on EXO's official Instagram account

Here's a surprise photo!

A post titled 'DECEMBER 2025' was also posted.

Wow.. that's really meaningful

Is it possible that EXO will make a full group comeback this December??ㅠㅠ

I haven't seen the article yet, but if this is true, it seems like a real hit..

Or, since it says MAMA, does it mean that they will appear on Mama Stage?
