By dropping the Movie teaser today instead of teaser for Lisa's solo, it's safe to say that her solo will be delayed indefinitely until after their Anniversary schedules.
They have by far the biggest girl group in the world, and coming off a hugely successful Album release last October, all they did for the first 8 months of 2021 is releasing Rose's solo. (The show doesn't count because it was delayed into 2021 due to Covid)
Can somebody go check the YGE building and see if there is even anybody inside?
