BTS held the 'BTS World Tour Ailee IN Busan' concert on June 12th at the Asiad Main Stadium in Busan, attracting approximately 100,000 fans. Five hours before the concert began, massive crowds had already gathered, with ARMY members taking photos with member banners and purchasing merchandise at the Sajik Indoor Gymnasium. Fans created a festive atmosphere by sharing handmade and purchased BTS goods with strangers, fostering a sense of unity. International fans from various countries including Nepal, Myanmar, and Indonesia attended the concert, with some enjoying Busan tourism while wearing hijabs. As the daytime temperature reached nearly 26 degrees Celsius, fans used purple hats and parasols to shield from the sun, while lines exceeding 100 meters formed in front of restrooms. A total of 3,043 safety personnel were deployed to manage the concert's safety.
