Lee Min Jung is certainly one busy girl these days. Having been chosen as the female lead in SBS Smile, You recently, Lee Min Jung was revealed to be participating in new group, December's music video together with actor, Kim Seung Woo. For the filming of the music video, Lee Min Jung and Kim Seung Woo had to soak themselves in rain (human induced) for 24 hours. Their professionalism was hailed by director Chang who is famous for being fussy. Director Chang made his directorial debut last Summer with Death Bell which had a good run at cinemas. This music video was his comeback work and Director Chang expressed, "I was highly impressed by Lee Min Jung and Kim Seung Woo's captivating acting and professionalism. Rather than thinking about the filming, I was more concerned about whether they will fall sick, from being soaked in the rain." Director Chang had kept re-doing the scenes until he was satisified as he added, "December are very lucky to have seniors like Lee Min Jung and Kim Seung Woo for their music video." Kim Seung Woo and Lee Min Jung were both busy with their respective schedules and had filmed the music video in very tired circumstances, but they still gave their all which won the applause from the filming crew. In a recent post-production meeting, Kim Seung Woo and Lee Min Jung were dissatisfied with some scenes and asked for another day to re-film them. After some rescheduling, Kim Seung Woo and Lee Min Jung will meet again on 17th August to film the music video again.
