UN (also known as United N-generation) was a Korean musical group from South Korea under NH Media (then NH Planning).
It consisted of two members: Choi Jung-won and Kim Jeong-hoon.
"For a Lifetime", a single from their first album, was their first significant hit.
[citation needed] In 1999, the two members, who are both from the top universities in Korea, formed UN but it wasn't until June 2000 that they released their first album.
In September 2005, 5 years after their debut and 5 albums later, their management agency, Laful Entertainment, announced that the duo would disband after the expiration of their contract.
