Red Velvet is finally making their long-awaited comeback y'all!

SM Entertainment just released a teaser MV for "One of Those Nights," the full MV for which will drop on March 16 at midnight (KST). In this short 24-second teaser, it's yet difficult to tell what kind of song or concept the girls are aiming for. Listening to the teaser, one may gather that it may not be a sprightly, lively, or a springy track but a mellow, serene one. If that's the case, then it will sure be nice change from their last upbeat and bouncy "Dumb Dumb."  

What do you think of this teaser?
