Just spitballing here, but I think Q is hinting that we pay attention to Kpop.
The "See you in Seoul" image had a member of SNSD in the image.
The repeated "Very very very" (a popular IOI song)
The Boom Boom (a viral & popular Momoland song)
This article about Momoland is interesting:

Also worth noting Kpop is SK Government psyop against NK. It's a celebration of capitalism and femininity, things that all Marxists hate (even the scum in our country, not just NK)
Also note SK blasts Kpop across the border and SK activists will fill water bottles with rice and usbs filled with Kpop music videos across the sea to the north.
I wouldn't be shocked if Twice's upcoming release isn't timed with some big news coming out of SK
It's called "What is Love?"
