Kim Se-jeong recently unveiled her first single album, “Solar System,” marking her long-awaited return to music following her 2023 full-length album, “Door.”
The track is a remake of “Solar System (태양계),” originally released in 2011 by Sung Si-kyung, reimagined through Kim Se-jeong’s distinct vocal color and emotional restraint. The release highlights her growth as a vocalist while honoring the quiet melancholy that made the original song resonate with listeners over a decade ago.
“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 Se-jeong said.
For the arrangement, Kim Se-jeong collaborated with singer-songwriter and producer Jukjae, who approached the remake with careful balance — preserving the song’s emotional core while exploring new interpretive layers.
“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 Se-jeong’s breaths,” Jukjae said.
Ahead of the single’s release, Kim Se-jeong appeared on the small screen in the historical fantasy romance K-drama “Moon River,” which premiered on November 7, 2025, on MBC and has just concluded its broadcast. The series tells the story of a crown prince who has lost his smile and a peddler who has lost her memories, bound by a love that transcends lifetimes. Kim Se-jeong starred opposite Kang Tae-oh in “Moon River,” which streamed on Viu in the Philippines and nearby countries.
Kim Se-jeong, an actress and singer under Jellyfish Entertainment, is one of South Korea’s most in-demand stars. Her notable works include leading roles in “Business Proposal,” “The Uncanny Counter,” and “School 2017.” She received the Asian Artist Award for Best Actor in both 2022 and 2023.
Beyond television, she has starred in stage musicals such as “Return: The Promise of the Day” and “Red Book.” She debuted as a K-pop idol in 2016 as a member of I.O.I before later joining Gugudan.
With her single album “Solar System,” Kim Se-jeong now turns her focus toward a new chapter, as the single signals the start of her 2026 activities, beginning with her upcoming fan concert tour, 2026 KIM SEJEONG FAN CONCERT <Tenth Letter>. The tour kicks off on January 10, 2026, in Seoul, followed by stops in Taipei, Melbourne, Sydney, Manila, Hong Kong, Kuala Lumpur, and Yokohama.
