Is this the debut of a trouble maker group from SM? Seems to be the case, with NCT 127 causing messes for the MV teaser of Fire Truck!
Giving off sounds different than what has been heard before from SM, the seven members march into rooms, seemingly there to help educate about firemen and fire trucks before they begin to wreak havoc and make messes as the audience just sits around doing nothing. The sound seems to be promising, so fans only have a couple days left before they can hear the new song.
