On November 5, Krystal sat down for an interview with the press.
Krystal said, "My sister and I really love and support each other, but we don't care about each other that much."
She laughingly continued, "I actually don't even know what she's up to these days. When I told her that I was going to act a pregnant woman, she was like, 'Oh, okay.'"
She resumed, "I think we just believe that we'll both do well with whatever we're given."
Krystal said, "I've never thought having my sister in the same industry would make me feel so much at ease. I don't think Jessica knew this either."
She went on, "Jessica understands me the most when I tell her my worries. I feel extremely lucky."
