The two debuted as Jinusean with the single, "Gasoline," in 1997 under the guidance of YG Entertainment CEO and former Seo Taiji and Boys member Yang Hyun-suk and former Deux member Lee Hyun Do. Their second single, "Tell Me" (featuring singer Uhm Jung-hwa), was the duo's first hit and propelled them to stardom.
