I'm looking for a bunch of artists social media handles.
It seems many of them stay anonymous but maybe some of you guys know at least a few?
Here's the list:

"Morak" -(K's Secret)
"Reck" -(Body Complex)
" GyaGa" -(I'm Yours, Blood and Soul)
"Ryuha" -(2020)
"Gangto" -(Backlight)
"Boy season" -(Codename Anastasia)
