Boom has sent a honest virtual letter to his good friend,�Rain. On the September 28th�broadcast of MBC's 'Radio Star', Boom shared a few words of advice with Rain, who will soon be enlisting with the army. Boom had heard that Rain congratulated him earlier on being discharged from the army, and so he responded in kind with a kind letter of his own. Looking directly into the camera, Boom said, "Ji Hoon [Rain's real name], it's me Boom, but you'll know me as Lee Min Ho [Boom's real name]." "We were close friends way back when we were students at Anyang High School, but then we grew apart." He mused, "it would have been great if you came into the army as a maknae while I was still commander there." Though Boom looked a little awkward while delivering his message, netizens were moved by his sincere message to Rain. "Please meet up again soon!", "How fun it would've been for them both to be in the army at the same time," and "I can't believe that Rain has to leave us so soon...", they wrote. Source + Image:�Nate
