its mostly me making sure i know my fave group's members names (the only ones i truly have trouble with is SVT outside of my biases from it tbh but then, all the members look so damn different i.e. Vernon and Woozi so i dont struggle as i used to with them lol)
i remember when i first heard about them, (as with other groups) i put all their names and pictures in my phone (in the notes section) just incase i forget (knowing my brain, happens more than often lol)
and even with groups that arent my faves, i try to know who y'all on here be talking about or on twitter be talking about (unless im tired and lazy then i wont even bother and keep mute) lol
