dear Jaejoong, when can we see this kind of performance again? You singing with no backing track is exceptional. I hope you do this in your recent concerts. His performance in 2013 with the live band is superb but his confidence here is like 200%,the way he danced, his walk, his outfit and his high note at the end is purely sensational. I have seen this many times but still reacts as if its my first time watching it.
