About the author


Hello everybody! You can call me Midge here. I've been an author on KProfiles since November 2019.

I like finding nugu (=super underrated) K-Pop artists. I think I've found some of the nuguest artists I could come across.

Unfortunately, I tend to be extremely forgetful and a master procrastinator, so I apologize for that.

I have a long-*ss bias list, so I don't think it can fit here.

Be nice and enjoy!
