A Special Comeback
Singer and actress KIM SEJEONG has released her first single album, Solar System. This is her first new music since her full album Door, which came out in 2023.
Solar System is a remake of Sung Si Kyung’s 2011 song “Solar System (태양계),” reinterpreted with SEJEONG’s own emotions and vocal color.
A Song Made with Heart
KIM SEJEONG shared that she poured a lot of effort into this release after being away from music for some time.
“Since I’m releasing a new song after a while, I worked very hard on this single in hopes of breaking the limit of my vocal skills! I hope many people could resonate with it.”
— KIM SEJEONG
Working with JUKJAE
The arrangement for Solar System was done together with singer-songwriter JUKJAE. The goal was to respect the original song while giving it a new feeling.
“We tried to keep the original mood, but express the sorrow as if it were the monologue of an actor just beginning their story.”
— JUKJAE
The track uses soft acoustic sounds to match SEJEONG’s breathing and emotional delivery.
Active on Screen and in Music
Before releasing Solar System, KIM SEJEONG starred in the historical fantasy romance drama Moon River, which premiered on November 7, 2025, on MBC. She continues to stay active both as an actress and a singer.

Solar System also marks the start of KIM SEJEONG’s 2026 activities. She will begin her fan concert tour, 2026 KIM SEJEONG FAN CONCERT <Tenth Letter>, on January 10, 2026, in Seoul.
