Noel's Lee Sang Gon sings this beautiful OST track for the latest Korean drama "Book of the House of Gu 구가의서", starring miss A's Suzy and Lee Seung Gi. This music video mainly portraits the heartwarming story of their parents which is played by actress Lee Yeon Hee and actor Choi Jin Hyuk. This is going to be another great Korean drama. =)
