So I recently found Amino thanks to Professor Oh, also known as SweetandTastyTV on YouTube.
There's tons of Kpop communities, but they have other communities like Books and anime and tattoos and piercings and so on.
They have pretty much any group you can think of. And all the communities have chat rooms so you can meet tons of fans. My profile is SayTheName_Kayla, and my pic is the gif of Amber laughing. ヽ(*≧ω≦)ﾉ
