(I prefer to use the older spelling and will use it throughout.)
BTS will have a concert at the Chamshil Olympic Stadium, which normally can house up to 55,000.
BTS' last concert there had 45,000 for 3 days. (The full capacity is rarely used in concerts because of the stage settings, etc.)
When it had a concert at the Sofi stadium last December, apparently it filled its 70,000 seats 4 days.
However, the K-O-R-E-A-N-S , with the law and order candidate Yoon Seokyoul likely to win the Presidential Election in two weeks and one of his first actions would be whisking Kim Seokjin away to the Military, are showing a much less lenient approach on concerts.
For the facility, the K-O-R-E-A-N-S are only allowing 15,000 out of a concert capacity of 45,000, even though Los Angeles had no trouble putting in 70,000 in a football stadium.
As a result, BTS will have the smallest capacity of anyone who had a concert at there, 15,000 each day. (The lowest record had been held by the balladist Lee Seunghwan who sold about 22,000 out of 30,000 seats scheduled.)
That led to the Singer who owns a $11.7 million condo to cancel her concert at the Chamshil, because she probably intended to fill it but the K-O-R-E-A-N authorities won't allow it. Her last concert at the Gymnastics Arena had 17,000 so she would hold less fans while performing in a bigger venue.
The Chamshil should have been renovated from 2020 but the suicide of the Mayor of Seoul after he was found to have sexually harassed interns postponed the renovation to I think around 2023. Once it is held it will last for 3-4 years if everything goes right.
That means if the Singer who contributed virtually nothing to Kpop's world conquest cannot hold a concert at the Chamshil this year she won't be able to hold it till at least around 2027, when she is 34 (human age) or 1,350 (since she might have been born during the T'ang dynasty of China around the year 680) years old.
Performing at the Chamshil is the greatest honor for any singer in K-O-R-E-A, and it seems the authorities finally realized it is not correct for a domesticist who can NEVER hold an arena concert, let alone a stadium one, outside of K-O-R-E-A to rise to the same level with the honored levels reached by BTS and EXO. (BTW the Effective Owner of Edam Entertainment is the first female singer ever to have attempted a concert there.)
