A mature viewing culture is just as important as the emotional impact of the performance.

Although BTS's concert in Busan concluded amidst intense interest and love, the trash issues that arose at some sites after the performance left a sense of regret. As it was a large-scale event that drew many fans from around the world, trash accumulated near the venue and in nearby areas, raising concerns about management issues.

It would have been even better if only beautiful memories remained after the performance ended, but the discovery of unorganized trash in some areas highlights the importance of a mature viewing culture once again. Of course, some degree of congestion and cleanup issues are inevitable in large-scale performances where numerous audience members move around at once, but these are aspects that can be sufficiently improved if everyone pays just a little bit of attention.
