She returned to Korea at the invitation of the South Korean government on 26 January 1962, after 37 years. At first, the South Korean government refused to allow the return of the last royal bloodline, because President
Rhee Syng-man wanted to avoid political chaos. After meeting her sister-in-law,
Empress Sunjeonghyo, the second wife of her older half-brother
Emperor Sunjong, she was admitted to
Seoul National University Hospital later that day for surgery to remove a polyp in the uterus. Despite being born in Korea, the princess was able to restore her Korean citizenship and finalized her name, Yi Deok-hye, on 8 February 1962, and was soon discharged from the hospital as her condition was proven stable on 4 May 1964. In the fall of 1968, she lived in Nakseon Hall,
Changdeok Palace, with
Prince Uimin and
Princess Masako, their son
Prince Gu, his wife
Julia Mullock, and Mrs. Byeon Bok-dong. Sometime before her death, around ten years before, her ex-husband flew from Japan to South Korea to visit her and see how she was doing, but this visit was rejected by her family. He begged Yi Gong-jae, a member of the family, to let him meet his ex-wife. But Yi said, "I can't forgive him for having an unwanted arranged marriage with King Gojong's daughter [a marriage that the head of the family or parental authority orders regardless of the person's will for their own benefit or purpose], eventually putting the princess in a psychiatric hospital and getting a divorce. The princess doesn't even have anything to talk about meeting him, and there's no reason for him to meet. If she met you, she would think of the past and make her condition worse. So, people like you are not allowed to visit at all, so please go back”. Her last years were filled with visits to different hospitals, but on 24 May 1983, she was admitted and stayed temporarily at
Hallym University Hangang Sacred Heart Hospital due to her old age. On 21 April 1989, the princess died at Sugang Hall,
Changdeok Palace, and was buried at Hongryureung in
Namyangju. Her burial site is near where her father,
Emperor Gojong, and older half-brother, Emperor Sunjong, are buried. == Family ==
