Following his official discharge from the military, MC/comedian Boom has already been receiving explosive "love calls" to appear on all sorts of variety shows. Yet TV viewers are most looking forward to his comeback episode on SBS's "Strong Heart" next week. Boom participated in a 'Strong Heart' recording this week, and it was reported that his variety show skills definitely didn't rust during his time away. His active participation in entertainment nights while in the army in fact helped him improve and refine his humor even more. While being interviewed on SBS's 'One Night of Entertainment', Park Sang Hyuk PD stated, "I believed that he could adjust well after his discharge without any special preparations; our directors also visited Boom during his time in the military every so often. There was even a moment when he signed a contract saying that he would come back to our show." Actor Lee Dong Wook, who spent his military period with Boom, also revealed, "What was really surprising from Boom was that he was already preparing for his discharge even during his enlistment. Every night before going to bed, he would write down ideas that came into his head in a notebook. It came to a point where he filled a entire notebook with his handwriting." Watch out for Boom's "Strong Heart" comeback this coming September 9th! Source + Image: Newsen via Daum
