Actress and Singer KIM SEJEONG Releases Her 1st Single Album, Solar System
NEW YORK, NY, UNITED STATES, December 17, 2025 /EINPresswire.com/ -- KIM SEJEONG has released her first single album, Solar System. It is a remake of "Solar System (태양계)” by Sung Si Kyung, which was originally released in 2011. This single is KIM SEJEONG’s first music release since her first full album, Door, released back in 2023.
“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
KIM SEJEONG worked with JUKJAE on the arrangement for this remake.
“While attempting not to ruin the atmosphere of the original song, we tried to reinterpret the track’s signature sorrow to that of the monologue of an actor who has just begun telling their story. How deep the meaning behind the lyrics and the breaths between the words still remains a mystery, and as such, the production process was a constant back-and-forth of ‘Is this the right tone? Is this how we progress here?’ Taking in how we attempted to express the sounds of the glistening planets with acoustic instruments, we hope you can feel as if you’re inhaling and exhaling in sync with SEJEONG’s breaths.” - JUKJAE
Ahead of this release of Solar System, KIM SEJEONG starred in the historical fantasy romance drama, Moon River, which premiered on November 7, 2025, on MBC. While her presence on screen is ever present for many viewers around the world, the release of the Solar System, marks the beginning of her 2026 promotions starting with her upcoming fan concert tour, 2026 KIM SEJEONG FAN CONCERT <Tenth Letter>, starting on January 10th, 2026, in Seoul, followed by performances in Taipei, Melbourne, Sydney, Manila, Hong Kong, Kuala Lumpur, and Yokohama.
