Interestingly that LMH was "to be" in kdrama High Kick and 9 End 2 Outs.
I maybe wrong but, he catapulated to fame from "Boys Over Flowers".. followed by "Personal Taste" then "City Hunter", "Faith" and the latest "Heirs"
And he just recently reached Hallyu star status, amazing how fans multiplied in Korea, especially in China and all over Asia. He did not start as a "hot Korean actor" but looks like he worked his way up slowly over the years.
You must have heard of his serious car accident in 2006 (he broke his leg and was implanted metal rods in his upper right leg and knee) that he had to stop his activities for almost a year which he was just to debut. In 2009, the surgery was to remove the rods.
In 2011 while filming "City Hunter" he again had a car accident (minor) the car was wrecked but he and a PD had minor injuries.
He loves his fans and makes it a point to smile, wave at the fans gathered at the airports waiting for a glimpse of him for hours. He is handsome!! what a lucky fella
