It's pretty safe to say that actress Song Hye Kyo and Jo In Sung are one of the greatest visual couples in a drama. A picture of the two actors from 10 years ago proved this to the online world.

Recently on a blog post, pictures of the two actors from 10 years were uploaded with the title "Song Hye Kyo and Jo In Sung's amazing visuals even in the past."

In the picture was Song Hye Kyo and Jo In Sung looking youthful from 10 years ago. The picture of Song Hye Kyo was during the 2003 SBS drama "All In." She looks no different from 10 years ago and still shows off her great visuals in 2013.

The picture of Jo In Sung was during his appearance in the 2000 KBS youth drama "School 3." He doesn't have the mature look he has now, but his distinct facial features were unique. His charisma seemed to be shown in his eye gaze and drew attraction even since the past.

Meanwhile, Song Hye Kyo and Jo In Sung are appearing as main characters in the new SBS Wednesday and Thursday drama "That Winter, The Wind Blow" as a power visual couple.
