The character from our fanart Among Us BTS BT21 Van Character Sticker is a big fan of k-pop. His favorite BT21 character is Van - the one with two colors, grey and white, which symbolize the world. The gray side means nighttime on one half of the world, and the white side means daytime on the other side of the planet. It also means that ARMY, BTS fans, is everywhere, whether it's west or east.
