Has anyone seen photos of the atmosphere near Gwanghwamun Square?
Ahead of the performance, there are also large buildings and the Sejong Center for the Performing Arts.
I started seeing promotional phrases for BTS's comeback.
It felt like the atmosphere in the city center had changed quite a bit.
Perhaps because it is a performance marking their return as a complete group after 3 years and 9 months
The scale of preparation seems quite substantial as well.
Because they said up to about 260,000 people could gather on that day
It seems like they are paying a lot of attention to crowd management.
More than 30 surrounding buildings are subject to management.
I heard that a request to control access to the upper floors has also been made.
I heard that some buildings even close the entire building on the day of the performance.
It seems they are also blocking things like rooftop or balcony viewing in advance for safety reasons.
Perhaps because it is a performance held in the middle of Gwanghwamun
It felt like the city atmosphere itself was gradually shifting into performance mode even before the event started.
It seems like there are quite a few reactions saying it's fascinating.
