SF9 member Yoo Tae Yang held a solo fanmeeting titled '2026 SF9 YOO TAE YANG FANMEETING "THE ROOM : Together"' on February 28 at Sungshin Women's University's Unjeong Green Campus auditorium. The event was held twice at 3 PM and 7 PM, and took on special significance as it occurred on Yoo Tae Yang's birthday, just three days before his military enlistment on March 3. The concert opened with 'Reality,' the OST from the movie 'La Boom,' followed by various segments including 'Play ROOM' featuring fan-voted cover songs and 'FANTASY ROOM' where a birthday party was held. The venue was filled with laughter and warmth through dance challenges, balance games, and photo time. A band live stage was particularly impressive, featuring SF9's 'Melodrama' and 'Don't Worry, Be Happy' in band arrangement versions, along with covers and unreleased original songs, filling the entire 120-minute runtime like a mini concert. In the second showing, SF9 members Young Bin, In Sung, Jae Yoon, and Hwee Young appeared as guests, delivering joint performances and talk segments that brought both emotion and joy to fans. At the end of the concert, Yoo Tae Yang expressed his gratitude, saying he would never forget the memories created in 'the room' and appreciated celebrating his birthday with fans while creating lasting memories. He then bid farewell to each fan individually through a hi-bye event.
