How is Sunmi currently doing in SK?

Not Korean.

But I recently looked for the gaon digital points of her last releases.

When we disco, her collab with JYP, is having good longevity, it's still charting on melon. It has more than 500 milion digital points iirc so I would say it's a hit.

Pporappippam has more than 300 milion digital points, so it did decently I would say but definitly not a hit.

Tail just has 90 milion digital points and I don't think it's charting anymore so it's fair to say it did not do well.

I am too lazy to search for the tweets wHere I saw these informantions, sorry.

Someone will probably provide you more precise informations.

Well I love how she’s always trying to top herself and release quality songs with amazing concepts. To go from Pporappippam to Tail is phenomenal lol.

Charting wising Pporappippam did better than Tail but her collab with JYP made her bag another hit.

Overall Sunmi still has quite the influence in Korea and will be on Girls Planet 999 representing the kpop masters with another top female idol, Tiffany.
