Davichi hit it big right away with their first single, a dramatic, folk-tinged ballad that showcased the full power of singers Kang Min Kyung and Lee Hae Ri. The South Korean duo's strong vocals blend together well, with Kang's huskier voice complementing Lee's lighter one. They quickly became known for poetic lyrics about love and longing, which add emotional depth to their repertoire of ballads and catchy, upbeat pop.
