On February 4, Yoo Ah In posted on his Instagram a poster of “Descendants of the Sun” that shows the main couple kissing, and includes the caption “#SongSong #Let’s Support Them” (the second hashtag was written similarly to how soldiers talk in Korea).
Yoo Ah In and Song Hye Kyo are both represented by the same agency, UAA (United Artist Agency), and known for their brother-sister relationship. He also is friends with Song Joong Ki from when they worked in “Sungkyunkwan Scandal” together.
“Descendants of the Sun” airs every Wednesday and Thursday on KBS2. Catch the latest episode on Viki!
