They censored the identity so it is suspicious.
Assuming it's true, the choreographer might be working on blackpink's comeback/tour, but BP doesn't use TBL's dance studio (they just record there).
It is most likely for Somi, but there's no way she's having a comeback soon when BP is coming back. So, Somi is probably preparing for a tour (she hasn't done any concerts yet for XOXO). Why? Because they wanted to coordinate with Blackpink's tour because Somi will open for them + some solo concerts, and they wanted to save up the hype for the main tour -> Teddy's annoying starvation strategy.
This would explain why Somi was teasing "crazy news" at the end of last year (artists usually start planning their tour after releasing an album). It could also explain why Somi had a couple Western YT promotions in February. They probably wanted to determine solo concert possibilities in the West (when touring with BP).
Update 2:
There doesn't appear to be any choreography for the X4 project, so Somi opening for Balckpink for at least one show still makes the most sense (not like ZionT and Wonstein were going to dance).
Update:
Somi will be part of project group X4 for the 2030 Busan World expo. They would probably use TBL's facilities to practice, so the choreographer could be working with them.
The World Expo is a giant exhibition/fair. Cities bid for it like the Olympics. One of Korea's themes will probably be related to kpop, so X4 is part of their bid.
So they are going for a power group with very popular artists in Korea (Somi has done some other government events in the past). Not to mention ZionT and Wonstein had a recent hit together with Merry-Go-Round.
