I have a problem, anyone have advice?

Okay, I’m a noob about Kpop and I’m just getting into it. The problem is that it’s hard for me to tell which member of a group is which. And honestly, I do get confused and it makes me feel bad that I can’t tell who is who (and this honestly goes to the Jpop fandom as well). So if anyone has any advice or anything I would really appreciate it, and thanks! :)
