She revealed, "In second grade, I was mostly unable to attend school and spent my days fighting a disease up to the first semester of third grade. A malignant lymphoma had appeared on my face around my lips, so I underwent cancer treatments for about a year and a half."

The singer continued, "At the time, I always took part in singing and art competitions with other children who were at the hospital with me. Now I am healthy," and smiled brightly.
