1983–2003: Acting debut and stardom
In 1983, Kim made her acting debut in a small role in the film The First Day of the Twentieth Year. In March 1985, she became an exclusive model for Hankook Cosmetics. Her full-fledged acting career began in 1985, after graduating from high school. After entering the Department of Theater and Film at Chung-Ang University, she starred in films such as My Love Jjanggu and Memories of Fire. Later that year, she took on leading roles in MBC Bestseller Theater - Unknowable Things and KBS Hometown of Legends, though she remained primarily known as a commercial model.
In 1986, while still a sophomore at college, she landed her first starring role in a television drama on KBS 1TV's daily drama A Woman's Heart. This was the first full-length daily drama planned by KBS since the previous year as a follow-up to Eunbit Yeoul. Industry officials noted that she was selected after beating out over 200 candidates due to her rich facial expressions and excellent acting ability demonstrated in Bestseller Theater. In the drama, she portrayed Song Da-young, a Korean woman who navigated the turbulent post-liberation era while prioritizing her devotion as a mother over her own needs.
Following A Woman's Heart, Kim focused on television dramas and emerged as a leading star of the early 1990s alongside contemporaries Chae Shi-ra and Choi Jin-sil. Among her most significant projects from this period were Beyond the Mountains (1991) and Sons and Daughters (1992), the latter of which earned her the Daesang (Grand Prize) at both the MBC Drama Awards and the 29th Baeksang Arts Awards. She also made an impact in cinema, achieving commercial success with The 101st Proposal (1993), a Korean adaptation of the Japanese television series of the same name, which garnered her Best Actress nominations at the 14th Blue Dragon Film Awards and the 32nd Grand Bell Awards.
In 1994, Kim took on the starring role in the MBC Monday-Tuesday drama Kareisky, which ran from December 19, 1994, to March 7, 1995. Written by Lee Sang-hyeon, the series anchored its narrative around Kim as Seong Nam-yeong, the central character whose journey drives the story. Her character searches for her lover, Yoon Sang-gyu, who fled to the Soviet Union due to unavoidable circumstances, while portraying the severe hardships faced after the family was forced to relocate to Central Asia. Adopting the Russian name Galina in later episodes, Kim's character ultimately became a maternal figure to Yoon's children following the death of their mother, culminating in a final scene where an aged Nam-yeong reunites with Yoon. For this performance, Kim received a Best Actress (TV) nomination at the 31st Baeksang Arts Awards in 1995.
Kim subsequently starred in the television series Love and Marriage, written by Kim Ji-soo and featuring an ensemble cast that included Kim alongside Kim Hye-soo and Lee Young-ae. Her performance earned her a nomination for Top Excellence Award for Actress at the 1995 MBC Drama Awards, followed by a win for Best Performer in the TV Actress category at the 8th Korea Broadcasting Producer Awards in 1996. Following her marriage that same year, she entered a three-and-a-half-year hiatus from acting.
She made her entertainment industry comeback in April 1999 with the MBC daily drama Only One You, after which she suspended her acting career once again.
