The sisters not only look similar but are also both actresses. However, Hyoyoung says there is a difference between the two. She explained, "Hwayoung is more of the sexy type, while I belong more to the sweet and proper side."
She continued talking about her sister, saying, "When we were young, we fought so much that people were worried for us, but as we got older, we came to let go of little things. At the end of this year, I want us two to drink wine at a fancy place and say things like, 'You and I have both aged. Let's work harder and better.'"
