Jeong Se-woon (Hangul: 정세운, born May 31, 1997) is a South Korean singer and songwriter signed under Starship Entertainment.
Jeong’s first public appearance was in 2013, as a contestant in the third season of K-pop Star. He passed the first round of auditions with a performance of his original song titled “Mom, Wait a Minute” (Hangul: 엄마 잠깐만). One of the judges in the show, founder and former JYP Entertainment CEO Park Jin-young, praised the musical form of the song and likened him to Akdong Musician, who were the winners of the second season of K-pop Star. Starting from the third round, he competed as part of the duo Something (Hangul: 썸띵) with fellow contestant Kim Ah-hyeon. The duo reached the finals but was eliminated during the first round of live performances. Three months after the show, Jeong signed a contract with Starship Entertainment.
In 2017, he represented “Starship Entertainment” in Produce 101 Season 2 alongside fellow trainee Lee Gwang-hyun. He became part of the Top 20 but was eliminated during the finale, after ranking 12th overall with 769,859 votes. After the show, on August 1, it was reported that he had started preparing for his solo debut.
Jeong debuted as a solo artist on August 31, with his first EP titled Ever, which peaked at number two on Gaon Chart after selling 23,438 copies within its first week. The album has two versions: “+Glow” and “+Green”. Both versions contain six songs, including his original compositions “Miracle” and “Never Mind” (Hangul: 오해는 마), as well as the title track “Just U”. “Just U” peaked at number eight and was digitally downloaded more than 59,790 times within the first week of sales.
