Boys Over Flowers is a 2009 South Korean hit television series that earned high viewership ratings in South Korea and popularity throughout Asia. It stars Ku Hye-sun, Lee Min-ho, Kim Hyun-joong, Kim Bum, Kim Joon and Kim So-eun. It aired for 25 episodes on KBS2 from January 5 to March 31, 2009.
Kim Soo Hyun could have been in Boys Over Flowers. During the first script reading of the drama, Kim Soo Hyun misread and over read the character Lee Jea Ha’s lines that was ultimately played by Jung Ui Chul in BOF. In BOF’s Japanese DVD, Kim Soo Hyung tried to explain why he read the line like that, but it wasn’t accepted well by the directer.
It happened during the starting of Kim Soo Hyun’s acting career, so we could say he was still learning. Anyways, we didn’t get to see him in Boys Over Flowers.
Here is the video of Kim Soo Hyun reading the BOF script.
