The Jung sisters are as sweet as ever!

On November 10, f(x)’s Krystal shared several photos on Instagram of herself posing in front of a coffee truck. The coffee truck gift was sent by Jessica to the filming site of Krystal’s upcoming film “Sweet and Sour” (literal translation).

In the caption, Krystal wrote, “Who has a big sis sweeter than mine.” She also showed off a sticker of herself posing with Jessica in another post, which was captioned, “I feel good.”

A banner next to the truck featuring photos of the Jung siblings reads, “Hang in there, staff and actors of ‘Sweet and Sour’! Fighting to Soojung [Krystal’s given name]. From, Jessica.”

It was previously reported on October 5 that Krystal will be appearing in the film “Sweet and Sour.” This will be Krystal’s first appearance in a commercial film, and she is currently also preparing for a leading role in her first independent film “Shouts of a Father” (literal translation).
