Get ready for a cozy winter soundtrack courtesy of Kim Se-jeong's captivating voice.

On December 17th at 6 PM, Kim Se-jeong unveiled the music and music video for her first single album, 'Solar System' (태양계), officially kicking off her musical comeback.

Having transitioned from girl groups I.O.I and Gugudan to a successful solo artist and actress, Kim Se-jeong has consistently proven her musical prowess, notably with her chart-topping debut solo track 'Flower Way' (꽃길). She continues to share her personal stories through her music, earning widespread acclaim as a singer-songwriter. Beyond her music career, Kim Se-jeong has also made a significant impact on the small screen, captivating audiences in dramas such as 'School 2017', 'The Uncanny Counter', 'Business Proposal', and 'The Flowing River'.

The newly released 'Solar System' is a remake of the 2011 hit song by Sung Si-kyung. Kim Se-jeong's rendition imbues the track with her unique emotional depth, delivering a gentle message to those who orbit a lost love at their own pace. Moving beyond the original's melancholy, she poetically explores astronomical metaphors of silently circling a distant object of affection, maintaining an unreachable yet devoted distance.

Kim Se-jeong's version of 'Solar System' masterfully blends her signature husky yet warm vocal tone with delicate acoustic piano melodies. Her rendition shines through poignant diction, as if savoring each lyric, and restrained, heartfelt vocals over flashy techniques. This approach not only honors the original's emotional core but also crafts a comforting song perfect for listeners during the winter season.

The accompanying music video complements the song's theme with a vintage, dreamlike atmosphere, utilizing a classic restaurant setting and antique props. Kim Se-jeong portrays an 'observer,' visually depicting the concept of 'revolution' (공전) by playing the piano or watching her dining companion from afar. Her elegant visuals, reminiscent of Audrey Hepburn, and the poignant representation of heartbreak through tears captured in a transparent glass bottle, amplify the song's bittersweet emotion through restrained acting.

Currently impressing audiences with her dual role in the drama 'The Flowing River', Kim Se-jeong solidifies her status as a 'vocalist you can trust' with the release of 'Solar System'.

Fans have flooded social media with praise for Kim Se-jeong's comeback. Comments include, "Kim Se-jeong's voice is perfect for winter," "On repeat!", and "The music video's atmosphere is incredible," showing high anticipation for this album.
