Seventeen choreographies

So Hoshi does all their choreos right? At least that is what Carats keep saying. How does he have time to do all that? That is a lot of work. Don't they have in-house choreographers too? Especially with $$ now that HYBE can fund Pledis. Super is just dance crew type of choreo like Royal Family. Just so so good.

I'm sure they have choreographers, I don't think hoshi could do all that himself, super's choreo is WILD (in a good way) the one thing I adore about seventeen is how good their choreography is.

Do they use foreign choreographers like Hybe, YG, or SM? I don't ever recall anyone saying they did.
