I just watched Weekly Idol 100th special with Rainbow, Secret, and 4 Minute. There was one question about who is the most good looking man idol just by looking his face. And one of the 4 Minute members, Jiyoon, said that D.O is the most looking idol. So I tried to make my personal ranking too. Here's mine (and it's only about face and it's only in SM Entertainment)

1. Super Junior Siwon

2. EXO Kris

3. EXO Luhan

4. DBSK Yunho

5. Super Junior Yesung

bonus:

I can't deny that he is also handsome:

Who are in your top 5?
