Jessica showed love for her little sister, saying, "Krystal always had a more kind image. At 3 years old, she had round eyes and pale skin, and even the young me thought she was pretty." Krystal also said, "Unni was pretty when she was younger, but I think she shines most right now. I think she's finding what's most like herself."

How sweet! The two sisters also look chic, feminine, and amazing on the cover. Don't you think?
