remember when we talked about how acts like Jessi, Hyuna and Heize don't really sell much physical copies and rather than that they were just charting well here and there with one or another song?
I think it's same case here
just seen that Somi sold 13k in 4 days
sadly this is what happen when you put soloist in a dungeon for way too long time
and then just think that few variety shows and music show performances will 'do a thing'
