The teaser for the Groovy Room-produced single, whose title literally translates to "Black Night," features black cats, full moons, and sensual tango dancing. Soyu is seen not only performing choreography with her back-up dancers, but sprawled across the top of a piano as she sings the song's hook.

'RE:FRESH,' as well as the full music video, are set for release on October 4.
