SS501 member Kim Hyun Joong was cast as the F4 member Hanazawa Rui in the Korean version of Hana Yori Dango, also known as Boys Before Flowers, which is scheduled to be broadcast via KBS 2TV in the first half of 2009 with a total of 24 episodes. According to an official from Group Eight, the production house in charge of the drama, Kim Hyun Joong was selected to play Rui, Ji Hoo (Korean ver.), because he was deemed suited for the character. The decision was based on his performance in the MBC program “We Got Married” where Kim Hyun Joong is being coupled with singer Hwangbo.

On October 2, 2008, an official announcement confirmed Hyun Joong as part of the cast for Boys Before Flowers.

Ji Hoo/Hyun Joong in Boys before Flowers:

Due to two of the members' busy schedules, Jungmin performing in a musical "Grease" and Hyun Joong filming a drama, SS501's album, originally due for release in late 2008, was to be pushed back to July 2009. Instead, a subgroup SS501 was formed. They initially wanted to use Triple S as their group name but gave up the idea because they think that they are 5 members always as 1 no matter what, so they continued to release a special project album U R Man (released on November 25, 2008) under the name of SS501.

Finishing their promotional activities for 'U R Man', they are currently promoting '내 머리가 나빠서 (Because I am stupid)', a song they sang for the OST of 'Boys Before Flowers'. This song is very well-received due to the success of the drama.

Because I am Stupid:

The original group, with all five members, is scheduled for a comeback in July 2009 and will have their Asia Tour starting at the same time. Asia Tour will include countries like Japan, China, Taiwan, Thailand, etc.
They will release their 2nd Japanese album in May 2009 titled "All My Love"
