With Jessica out of the group, Yoona can finally enjoy being the best looking member in SNSD. These days I mainly watch SNSD's MVs just to look at Yoona, and it's a shame that I always need to mute the MVs.
I've never really understood the "Yoona is overrated" saying. I can understand it coming from Hyoyeon, Sooyoung and Sunny fans, as they need to attack the face of the group to make their favorite look better in comparison. But everywhere else I go outside of the SNSD thread on One Hallyu is full of people shitting on Yoona.
I don't know, maybe you inferior non-Koreans just can't appreciate Yoona.
