However, due to family opposition and practical conditions, she could not receive professional training, so during high school she trained herself in singing and dancing.

At first she obeyed his wishes, however, she was unable to endure being a college student and eventually left her hometown to pursue a dancing career. She did not speak with her father for the next seven years. She went to Seoul alone and without funds. One day a friend took her to an interview to be a backup dancer.
