Entertainer�Boom was recently discharged from the army, and is currently getting ready to retake the industry with his numerous new jobs. Now that he's taken up two new positions as an MC and a DJ, many began to wonder how he'd find the time to nurture his relationship. Unfortunately, it seems that he's broken up with his girlfriend. According to a source in the entertainment field, Boom and his girlfriend ended their relationship while he was serving his country towards the end of 2010. Because Boom couldn't see his girlfriend often, and since his girlfriend was busy with her personal life, they naturally ended their relationship. A representative from Boom's agency stated, "Boom and his girlfriend's relationship ended midway through Boom's military service. Why and when they broke up is something we don't know." Before being enlisted in the army, Boom proudly revealed his relationship through a TV show. During a press conference, he said that, "I got on my knees and begged my girlfriend to wait for me". He later shared his pet name for his girlfriend, 'my sobbabba', during SBS's Entertainment Awards, where he received the rookie award in the variety field. Boom said that "At the training camp, I received 17 letters from my girlfriend", and asserted that there were no problems in their love, just that they couldn't maintain it during his army vocation.
