SECRET's member Song Jieun revealed her slender body from her diet.

On October 24, Song Jieun posted on her Instagram, "Person present" along with a picture.

In the picture, Song Jieun is wearing a button-up shirt with a ribbon in the front, frowning at the camera. Her delicate shoulders and arms seemed to have gotten even thinner through her recent diet.
