Actor Jang Geun Suk would not have been cast as the most beautiful man in the world for "Pretty Man" if he did not fit the bill, and photos from his childhood to present show just how much of a flower boy he is.

Several pre-debut photos of the actor have been circulating the web and gaining attention over the past days. From his early drama portrayals to his actual photos from school, it seems that he has always been a beautiful man. Jang Geun Suk is already in his mid-twenties, but comparing his current look to his appearance as a child, he still wears the same gentle and innocent smile as he had all those years ago.

His drama "Pretty Man" premiered on November 20 with an average rating of 6.3%, but despite rating higher than "Medical Top Team's" 5.7%, it was not able to beat "The Heirs", the new reigning Wednesday-Thursday drama.

"Pretty Man" is based on the original manhwa of Chun Kye Young. It is directed by Jung Jung Hwa from the "Flower Boy" series and written by Yoo Young Ah from "No Breathing".

Catch Jang Geun Suk and the cats of "Pretty Man" every Wednesdays and Thursdays on KBS.
