Fans of Song Joong Ki and Song Hye Kyo feel that the duo is hiding their relationship from the world. The Descendants of the Sun are known as the #SongSong couple and has been trending across Facebook, Twitter, and Instagram.

During an interview with Harper's Bazaar, the 30-year-old actor revealed that he is not comfortable talking about his love life. He said: "My dating style is not that special. But I have no plans to go public if I get into a relationship. I will do my best to preserve the emotion for the person that I like but I also want to keep it secret for that person."

Rumours that they are romantically involved started in March after the two were reportedly seen together in New York. Joong-ki's agency confirmed that the couple is not an item in real life. The statement from UAA Korea read: "Song Joong-ki is her good colleague with whom she's done a TV series together."

"She was on vacation in New York and Song Joong Ki happened to be there. They had a meal with other friends, and we cannot believe it has turned into a scandal. There is no need for us to consider it seriously. We will take it as a sign of fans' interests. That story has been going around for a long time now. Media outlets have asked us about it and we have told them many times that it is not true," the letter read.
