anyone saying BTS will flop with this comeback is utterly delusional lmaooo, anyways breaking a Taylor Swift record is HUGE, she's THE #1 female popstar of this generation AND has the biggest fandom, actually ARMYS are the only fandom who has any possibility of competing against swifties when it come to pure core fandom numbers, and BTS is the only artist capable of coming close to the eras numbers (if they add even more dates and tour for a long time on stadiums over the world like she did).
They most probably would, middle east and more japan dates are coming according to announcement. Probably one or two days in India too.
