Kim Hyun Joong was attending KARA's concert (KARASIA) in Seoul, February 19th 2012. Other SS501 members Heo Young Saeng and Kim Kyu Jong were also came. So happy to see Hyun Joong showed up in public again. We miss him so much, don't we? ^___^
SS501 and KARA used to be in the same management DSP. The concert building is the same when PERSONA concert of SS501 was held in August 2009 and February 2010.
