[1][2] Kim's mother, Ga-young, first enrolled her and her sister Yu-seong into figure skating when they were eight years old as a means of improving their health and growth.

Due to the lack of skating rinks where they lived, the family moved to Gwacheon in 2019, where both sisters began training under Choi Hyung-kyung.

Kim attempted a triple Axel in the free skate, a rarity among female skaters, landing it a quarter underrotated.

She finished fourth in the short program with a new personal best, despite receiving a quarter underrotation call on her triple loop attempt.

[5][6][7] In late July, Kim competed at the 2023 South Korean ISU Junior Grand Prix Qualifiers, where she finished sixth.

With this result, both Kim and her sister, who finished fourth at the event, were selected to represent South Korea at the 2024 World Junior Championships.
