Glass Slippers () was a 40-episode South Korean drama series that aired on SBS in 2002, starring Kim Hyun-joo and Kim Ji-ho as the two orphaned sisters. Plot 6 year-old Yoon-hee and her elder sister Tae-hee were raised by their widowed father. Their mother had died giving birth to Yoon-hee. After years of struggles, their father who had already suffered from cancer was killed in a car accident, leaving the girls with no choice but to find their rich paternal grandfather who lost touch with them due to his disapproval of their mother. At the train station, they were robbed by a group of gangsters. Tae-hee, while chasing them, did not notice that Yoon-hee, who followed her, got knocked unconscious by the Oh family's truck. Tae-hee got beaten by the gangsters and was helped by a boy named Jae-hyuk until both got to see her grandfather. They looked for Yoon-hee in despair, unaware that she has lost her memories after regaining consciousness and moved away with the Ohs. Based on the name carved on her mother's ring, Yoon-hee assumed that her name was 'Sun-woo' and used it as her identity. 15 years later, Tae-hee works in her grandfather's company, and is romantically involved with her childhood crush and co-worker Jae-hyuk (unbeknownst to Tae-hee it was Jae-hyuk's revenge plan on her grandfather who had indirectly caused his grandfather's death years ago). In contrast, Sun-woo grows up in the Oh family and often gets abused (especially by Seung-hee). She almost gets raped by Seung-hee's step-father thus gets kicked out of the house by his wife. Seung-hee's crush Chul-woong has desires on Sun-woo, so he lets her take refuge at his home. Tae-hee, not giving up on finding her sister, tracks down the Oh's address and confronts Seung-hee upon seeing her wearing Sun-woo's ring. Quickly learned that Sun-woo is Tae-hee's long-lost sister, out of jealousy and greed, Seung-hee pretends to be Yoon-hee and moves in the Kim's family. Tae-hee seems happy while her grandfather remains suspicious of Seung-hee. He overhears Seung-hee's phone conversation with her mother and right away exposes her deceptive plan. However, Seung-hee lied that the real Yoon-hee's fate is unknown, not saying a word about Sun-woo. He is devastated thus decides to keep the truth from Tae-hee. Coincidentally, Sun-woo gets a job in her grandfather's company and frequently interacts with Tae-hee and the grandfather. They are fond of Sun-woo until
