Yes, he was commited suicide in 3 July 2013 but … .
Because I love The King 2 Hearts so I have to mention his name. It was his company, Kim Jong Hak production which produced The King 2 Hearts. If he didnt set up Kim Jong Hak production, maybe there would no be The King 2 Hearts.
Sometimes, I just wanted him to be a moslem so he would never choose to suicide. My religion does not allow suicide because it is a big sin. If he knew Islam, maybe he would never choose to suicide.
Please, read his biography here: http://en.wikipedia.org/wiki/Kim_Jong-hak
