BTS's Jungkook gave fans an unforgettable surprise when he attended Stray Kids' RUN IT World Tour concert in Seoul on July 26, showing up as a fan to enjoy the performance from the audience.
Keeping a low profile, Jungkook sat beside his longtime manager with no mask covering his face, smiling, singing along, and soaking in the high-energy show. Many fans believe he attended to support his close friend Bang Chan, Stray Kids' leader and fellow member of the famous '97-liner friendship group. Their friendship has been well documented over the years, from Jungkook publicly praising Stray Kids' music to Bang Chan attending BTS's world tour kickoff earlier this year.
As fan-captured videos spread across social media, ARMY and STAY celebrated the heartwarming crossover, praising the genuine friendship and mutual support between two of K-pop's biggest groups.
But one unexpected moment quickly stole the spotlight.
During the concert, Felix tossed his sunglasses toward the audience as a gift for fans. Instead of reaching the crowd, they landed on Jungkook's bodyguard, leaving him visibly confused as he carefully removed them before handing them to Jungkook.
Jungkook burst into laughter, casually put on Felix's sunglasses, and continued dancing and enjoying the concert, sending fans into a frenzy. His playful reaction instantly became one of the most talked-about moments of the night, with clips of the incident going viral online.
For many fans, it wasn't just the funny sunglasses mishap that made the moment special—it was seeing one of the world's biggest stars simply relax, laugh, and enjoy a concert like everyone else. Jungkook's genuine excitement and carefree energy reminded fans that, beyond the spotlight, K-pop idols are also fans who love supporting their friends.
The wholesome interaction between Jungkook, Bang Chan, and Felix quickly became a favorite memory from Stray Kids' Seoul concert, highlighting the strong friendships that continue to connect artists across the K-pop industry.
