She was recently a guest on 'Pot Stand', where she reviewed books as a reader. When asked why she read so many books, she revealed, "When I had hard times, I didn't have anyone to talk to. So I got advice from books and gained strength."
After reading Heechul's book about girl groups, she said, "The book talks about the pains of having a really busy schedule. However, the real hard times are when we have no work. I hope you can tell the story of girl groups who don't have work."
