Nowadays you have everyone and their mothers thinking that every kpop group should do arenas in the west. Ya'll know the weekend right? the one of the biggest artists in the US, he's struggling to sell out arenas rn. ya'll know Olivia Rodrigo? The biggest GenZ popstar rn, she's doing theaters.
BP who are arguably 10x more popular than any kpop sans bts in US back in 2019 was struggling with arenas. Even Ariana grande
BTS didn't do stadiums until they started to sell out 3-4 arenas back to back at a same place.
Every 4th gen group stan thinks that their favs will be like Bts overnight but BTS is truly an anomaly, their success was something no one anticipated, no one.
