Why it's so hard for people to accept Yeri, I think ot5 is better she add something to the group because she have this cheerful personality. berfore I think that RV is a bit boring. (dont hate me) People hate her because SM added her after they debut, what if they added her before they debut people will just accept her. and you know there's a rule in Korea about underage workers so that's why they added her after she turned 16 sorry for my bad english.
