Red Velvet, the rookie group that has been spreading 'happiness', will be returning sooner than expected!

They'll be releasing the digital single "Be Natural", which is actually the remake of former SM Entertainment girl group S.E.S's song by the same title! Seulgi and Irene performed this song before through a pre-debut SMROOKIES clip, but now we'll get to see how all 4 members will present the song.

Judging by the teaser released above, it seems we can expect a completely different image from the girls who previously brought smiles with their cheerleader-style outfits. 

The release is set for the 13th so mark your calendars!
