In 1994, he started the band Toy as a duo with Yoon Jeong-oh. But after releasing Toy's first album, Yoon left the band to study overseas and You joined the navy for his mandatory military service. Since 1996, Toy has continued as a one-man band with You as the sole member. After his discharge from military service, Toy's second album "Fairy Tales for Adults" was released, with the title song "Remember I Was Next to You" sung by Kim Yeon-woo becoming a big hit. Since then, You has rarely sung the songs in his albums and instead features guest vocalists such as Kim Yeon-woo, Kim Hyung-joong, Lee Jang-woo, Yoon Jong-shin, Kim Jang-hoon, Jinu (also known as Hitchhiker), and Byeon Jae-won.
