Since uploading her first picture on April 8, Krystal has mostly uploaded pictures of herself and f(x) members but on April 12, she uploaded a different picture. This time it was a photo of her and her sister, Girls’ Generation’s Jessica. Collectively known as the Jung Sisters after their last name “Jung,” this family has received a lot of attention and jealously for having good-looking genes.
The childhood photo shows Jessica, the older sister, back-hugging Krystal. She might actually be trying to piggy-back on Krystal, as baby Krystal does not look exactly pleased in the photo. Krystal included the caption, “late national siblings day- love u jess <3,” displaying her affection for her older sister.
