Have you ever noticed how SM recycles voices and faces???


Facially:

Tony Ahn --> Yoochun
Donghae --> Amber
Stephanie Kim --> Zhang Liyin --> Tiffany (Stephanie) Hwang
Siwon --> Suho
Taemin --> Kai
BoA --> J-Min
Han Geng --> Lay
Jaejoong --> Kris
Jang Woo-hyuk --> Eunhyuk
Lee Min-woo --> Henry Lau

Vocally:
Stephanie --> Zhang Liyin
Changmin --> Baekhyun
Jonghyun --> Chen
