NCT's sub unit NCT 127 have release a sick teaser MV for "Fire Truck"!
The teaser shows the members wreaking some havoc in what looks to be a classroom and an office, evidently out to disturb the peace and quiet. I mean the song is titled "Fire Truck" and they're kind of known to be loud so I suppose NCT 127 are sticking with an equally loud and bombastic concept. And I'm liking the sound of it so far!
Make sure to check back for the full release!
