Yun Yo Sep, known professionally as Joseph, is a South Korean singer and member of 4MEN (포맨). He graduated from the Seoul Institute of the Arts with a bachelor's degree in Applied Music.

Before debuting, he was working part-time at a convenience store and a video of him singing while at the counter went viral. As a result, he appeared on "Star King" singing a duet with Shin Yong Jae.

He made his debut as a soloist in 2016 with the single album "B&W" and featured in a few songs by other singers such as Ben and T-ARA's Ji Yeon.

In 2021, he decided to join 4MEN. The group had debuted in 1998 but underwent several lineup changes. The agency, MAJOR9 (메이저9) decided to revamp the trio and added him as part of the 4th generation alongside Ha Eun and Hanbin, releasing the first mini-album, "The Eternal".
