[About JJ's passion for acting... from the words of Song Seungheon in his recent interview]
"When we were making Dr. Jin,
I asked to Jaejoong why you do acting-it's because you really want to do it or have to do it..
He answered he really wants to do it.
Watching his attitude, he was trying to his best than anyone else.
I also saw his hard work and his passion.
He has much passion for acting than anyone else.
I think his attitude and passion will naturally help and make the advances of his acting level."
