Thunder guested on SBS powerFM's 'Kim Chang Ryul's Old School' on December 15!
He had joined agency Mystic89 after leaving MBLAQ, so he was asked whether he had any celebrity friends in the company yet. He revealed, "I recently got a bit closer to Eddy Kim because we're the same age. We got closer while also playing games."
