In Round 1 of the Run BTS! Telepathy special, the keyword was 'kkuljaem' (super fun). J-Hope chose Jamsil Main Stadium without hesitation.

"When I think of 'kkuljaem,' concerts come to mind. It's a precious place where we were with ARMY," he said. He recalled the sea of ARMY Bombs he saw from the stage as the first thing that came to mind. "The ARMY Bombs spread out like that—that's the clearest memory."

Ultimately, at the end of the round, all six members except V gathered in front of Jamsil Main Stadium. "This is legendary, isn't it?" the members said, looking at each other. V, who was alone in Cheongdam-dong, received a video call. This was because V had gone to a different location, the place where he first met ARMY at a showcase. The group photo taken by the members in front of the stadium that day was posted on Jin's Instagram.

BTS's connection with this stadium began in August 2018. They first performed on the Main Stadium stage for the Seoul stop of the LOVE YOURSELF tour, marking their first entry into Jamsil Main Stadium since their debut. In October 2019, they returned for LOVE YOURSELF: SPEAK YOURSELF THE FINAL. After traversing Wembley and Stade de France, they performed the final stages of their world tour at this stadium for three days, with a total of 129,268 people attending. In March 2022, they returned to this venue for PERMISSION TO DANCE ON STAGE - SEOUL, their first in-person concert in Seoul in approximately two and a half years since the COVID-19 pandemic.

To date, they have held a total of eight solo concerts at Jamsil Main Stadium alone. That scene, looking down at the stadium filled with ARMY Bombs, is why it's the first image that comes to mind for the members when they think of 'ARMY.'
