Jung Sung Yun, known simply as Sungyun, is a South Korean singer, dancer and member of N.SSIGN. He had a dream of becoming a singer since he was 17 years old and, in early 2022, he became a trainee at Yes IM Entertainment after being part of Wannabe Academy. Later that year, he entered the singing competition "Stars Awakening" produced by South Korea's Channel A and Japan's ABEMA.

He was part of team idol who were declared the winners and, as part of the Top-7, he was allowed to debut as a member of a boy group, initially called YOUTH STAR and later changed to N.SSIGN, under n.CH Entertainment. They released a pre-debut mini-album, "Salty", and held some concerts in Japan and South Korea. Originally, the company planned it as a 2-year project group, but after several discussions it was decided to make it a permanent one.

He officially debuted as the group's main vocalist and dancer in August 2023 with the album "Birth of Cosmo".
