Girl group Five Dolls Hyoyoung took a picture with her twin sister Hwayoung.

On August 11, Hyoyoung posted on Twitter, "Let's get prettier by working out. Let's get healthier."

In the picture, Hwayoung and Hyoyoung are together laying down and taking a picture. Their makeup-less faces and perfect flawless skin stood out in the picture.

In response, people said, "Get prettier together", "Fighting Ryu sisters", and "I miss you both so much".

Hyoyoung recently was on the JTBC drama, "Dale that became soup" that ended in June.
