At debut, they were constantly referred to as "BTS brother group" "BTS' hoobaes", etc, etc. And not as TOMORROW X TOGETHER.
I hate when I see the "ARMYs stan TXT" excuse for their success, because while that may have been true at the beginning, TXT are thriving off the support of MOAs and MOAs only.
If anything I am seeing more JPOP/Anime fans stan TXT these days(And it makes sense with their activities in Japan, their OSTs, etc)
TXT aren't getting all these OSTs and big deals because they're BTS younger brothers, TXT aren't breaking and setting records because they're BTS' younger brothers, they're doing so because they're TEE EX TEE
