On the 21st, when BTS's comeback stage is held, spectators began entering the venue around Gwanghwamun Square in Seoul.
The seating prepared at Gwanghwamun Square totals 22,000. Entry to the assigned seats and standing area in front of the stage began at 3 p.m. that day.
The standing area on the south side of Sejong-daero toward City Hall will be opened in sequence starting at 5 p.m. "ARMY (BTS fandom)" members who could not get seat tickets have been waiting to enter since early morning to secure spots close to the screens.
According to Seoul's real-time urban data, as of 3 p.m. that day, the floating population around the venue was 26,000–28,000. The current congestion level is "light," but it is expected to rise to "moderate" starting at 4 p.m.
The real-time floating population is calculated based on signals from users of telecom operators KT and SK Telecom, adjusted for market share and other factors. Considering that many foreign ARMY are on site that day, the actual floating population is likely higher.
The number of personnel deployed for safety management also reaches 15,000: about 6,700 police, about 800 firefighters, about 2,600 from the Seoul city government and district offices, and roughly 4,800 from the organizer.
