Hmm interesting, I didn't know about this since I rarely watch Idol championships.
Let's be honest, who wouldn't love Eunji ?
Yeah I was a little tired when I wrote that lol. I was getting my words mixed up and just kinda through those in there. Though, those terms aren't constant so Naeun, Eunji or Ilhoon could be the centers. Just depends on what point in their careers the groups are. Even that said, I'm not sure who really is the center of APink haha..I don't that much about them tbh
Center = visual, right? If so, Naeun is the visual.
Yes Naeun = centre/ visual
Eunji = face/ most popular
People assume centre and face mean the same thing (sometimes one person is both aka Suzy but it's different in most groups)
