Singer and actress Kim Sejeong is ramping up comeback momentum by releasing concept films and concept photos for her first single "Solar System."

The concept film and photos for the first single "Solar System," which were released sequentially starting on the 12th, visually convey the mood of the song on the single album 'Solar System.' Each version captures a different mood and narrative, vividly revealing Kim Sejeong's unique "Solar System" atmosphere.

In the "Atelier" version concept film released on the 12th, scenes show her holding a teacup in an exotic atmosphere and looking at an empty seat, drawing attention with a sophisticated elegance reminiscent of Audrey Hepburn.

Next, the "Chamber" version concept photo released on the 13th completed a mysterious yet dreamy image with scenes of her naturally lying on a sofa and staring straight ahead with an empty expression in a dreamy atmosphere.

In the subsequently released "Chamber" version concept film, calm scenes of her staring into space with an empty expression and natural moments continue, further heightening curiosity about the first single album "Solar System."

The concept photos for the single album "Solar System" expressed completely different moods for each version, revealing a variety of charms. In the "Atelier" version, she completed a classic image unique to Kim Sejeong within a refined and elegant mood, and in the "Chamber" version she presented another tone with a hollow expression amid a dreamy and secretive atmosphere. Through the single album "Solar System," it is expected that listeners will feel a different charm within Kim Sejeong's boundless musical world.

This single album "Solar System" is a work that reinterprets Sung Si-kyung's original song released in 2011 with a new sensibility. While preserving the original song's atmosphere, Kim Sejeong's delicate expression and a new emotional line will be added to complete another story, and anticipation is building over what color "Kim Sejeong's Solar System" will be filled with.

Meanwhile, Kim Sejeong is showing diverse acting, from the warm and lively Bu Bosang Park Dal to the wistful and tragic warm royal consort Kang Yeonwol in the MBC Friday-Saturday drama Moon River, and to mark her 10th anniversary next January she will hold a fan concert tour, "2026 KIM SEJEONG FAN CONCERT 'The tenth letter'," in eight global cities including Seoul. The first single album "Solar System," her first release in two years and three months, is scheduled to be released at 6 p.m. on the 17th.
