On December 2nd, Tomorrow X Together (TXT) hosted one of their two finale concerts for the "ACT: SWEET MIRAGE" tour at the Gocheok Sky Dome in Seoul. This event marked a significant return to the stage nearly four months after their previous "ACT: SWEET MIRAGE" performance.

The concert drew a substantial audience, including notable attendees Han Seung-yeon, Nicole, and Gyuri from the legendary second-generation girl group KARA.

TXT's leader, Soobin, has openly expressed his admiration for KARA. His fandom became particularly evident when KARA celebrated their 15th anniversary earlier this year with a reunion. Soobin attended their fan meeting, demonstrating his support for the group. Additionally, during KARA's promotion of their special 15th-anniversary album, Soobin took the opportunity to personally deliver letters to the members backstage at a music show, further solidifying his admiration for the group. Notably, his favorite KARA member, Seung-yeon, ranked this encounter among her top three moments experienced during KARA’s special comeback period.

The presence of the three KARA members at TXT's concert was highlighted by their posts on social media, sharing photos from the event via Instagram Story.

Soobin has yet another successful fanboy moment.
