The popular on-screen couple of the "Descendants of the Sun" Song Joong-ki and Song Hye Kyo are lately posting contrasting pictures on their respective instagram accounts -- amusing, or rather bemusing the fans. While Song Hye Kyo images are depicting that she is sad, the recent pictures of Song Joong-ki shows him in all smiles.

However, the recent Instagram post of Song Joong-ki on Wednesday raised some questions as in the picture there was an anonymous woman. The picture is of Song Joong-ki talking to a woman, whose back is turned to the camera. It appears that the two are in a serious conversation. It is difficult to guess who she is as Song Joong-ki did not caption the picture as well. But, the post got over 130,000 likes and more than 500 comments.

Fans and followers are really eager to know about the mystery woman in the picture. Some of his fans even asked, "Who is she? Some inquired, "New drama? New movie," However, there was no reply from the "Descendants of the Sun" star Song Joong-ki. Well, it can be a promo for his new drama or may be a movie.

Although, according to Yibada, neither does it seem that the scene is from "Battleship Island," which is his next movie nor it is from the speculated "Descendants of the Sun 2" which has not been confirmed by his agency or KBS.

A few days earlier, the actor posted a photo of himself wearing the army uniform which he used to wear in "Descendants of the Sun." Fans started speculating that the sequel of the popular series is in the works.

Since it is not known, it can be that the unknown woman in his recent post is none other than Song Hye Kyo. Well, whoever it is, until and unless Song Joong-ki identifies her, the fans will remain restless.
