It’s not really an encore performance, I just don’t know what to call it xP.
I love this song so much. I’m really glad they decided to promote this song too. You can see Hannie’s bow tie is undone XD. BUT OMG THE PART WHERE TEUKIE TOOK HIS JACKET OFF AND YOU CAN SEE THROUGH HIS SHIRT; hahahaha the fans went wild. And then Eunhyuk was grinning like crazy, Kangin kind of went o_o and then smiled and Ryeowook kind of put his arm around him when he went to the front XDDDDDDD. I keep on replaying 2:38 onwards ^__^. Ahhh, I love SuJu so much :).
