About the author


I like finding nugu (=super underrated) K-Pop artists.
I also like procrastinating for some reason...

I can make artist profiles (singers and even actors or dancers), polls, Who is Who? and a lot more based on your requests and my personal will.

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

Be nice and enjoy!
