It looks like the Dirty Walk music video was filmed at the Hyundai Steel Plant in Dangjin.

Anyway, aespa also filmed the 'Dirty Walk' music video here last year.

I had a feeling that might be the case...

Anyway, that was exactly the metallic taste unique to aespa...

It feels like it fits the title 'Dirty Work' too? lol

Now that I think of it, I should go rewatch the music video too haha.
