https://twitter.com/aespa_Official/status/1320394799162118145?s=20SM released a teaser for something called "Aespa". People believe it to be either a new SM girl group, a female SuperM or some type of SM competition/show that has been in the works.
In the past when SM had scandals/controversies they usually end up debuting new groups to draw attention away, putting their older groups on the backburner. Red Velvet might be about to pull an f(x).
