Ji Yun Seo is a South Korean singer, dancer, and former member of EVNNE (이븐). He graduated from Toegyewon High School and is currently enrolled in the Broadcasting Entertainment program at Global Cyber ​​University.

Before debuting, he spent 2 years and 4 months as a trainee at YH Entertainment (YH엔터테인먼트; formerly known as Yue Hua Entertainment).

In 2023, he entered MNet's "Boys Planet", but he ended up in 41st place. However, Jellyfish Entertainment (젤리피쉬엔터테인먼트) reached an agreement with several agencies and decided to create a second project group (alongside ZEROBASEONE) with the contestants outside the Top 9. Originally, the group's name was set to be BLIT (short for "Boldly Leaping into Tomorrow"), but after careful discussions, it was decided to change it to EVNNE (short for "Evening's Newest Etoiles").

He made his debut in September 2023 with their first EP, "Target Me". According to his original contract, the project was planned for 18 months.

In December 2025, Jellyfish announced that it had reached a new agreement to formally continue EVNNE as an established group. However, YH did not agree to these terms, and as a result, he had to leave in January 2026 and return to his agency.

On February 13, 2026, he had concluded his exclusive contract with YH Entertainment through a mutual decision.
