For those who have watched T-ara's Bo Peep Bo Peep performance on Music Core yesterday,you must be surprised with a mysterious voice that appeared at the beginning of T-ara's Bo Peep Bo Peep performance.

The voice belongs to no other people but 2PM's main vocal,Junsu!

I was thinking that that mysterious voice belongs to taecyeon as he is getting dorky nowadays,but the truth proved me wrong as Junsu also has dorkiness sometimes,he is really cute enough to join T-ara as the 7 th member in my opinion,do you agree with me?
