As his natal day is about to end, Hyun Joong posted a handwritten message on his Korean Official Board [hyun-joong.com/bbs/view.asp?code=fromhj].
Here is the translation of the short message that I lifted from the tweet of @5StarsAs1.
I've spent a wonderful day reading the birthday messages that everyone have sent. I will work hard to become a better person.
Thanks to @iamsom for the image
