A childhood photo of the sisters, Girls' Generation Jessica and f(x) Krystal, has been revealed.

On April 12, f(x)'s Krystal posted a photo via Instagram with a caption, "Late national siblings day-love u jess sister."

In the photo are the lovely sisters embracing each other at the beach. Jessica is doing all the embracing for the both of them, to be exact. In fairness to Krystal, who apparently did not enjoy pictures as much as Jessica, let us be reminded that none of us liked to take pictures when we were little.

Internet users have commented, "So beautiful and precious" and "Lucky parents or lucky children?"
