Some onlookers at the event said that the rumored couple was seen warming up to each other. In fact, their body language in each other's presence was that of a romantic couple. Song-Song duo was also spotted stealing dreamy glances, one too many times.

According to Soompi, Hye Kyo was seen comforting her rumored beau after he cried following Park Bo Gum's award acceptance speech. Despite rampant rumors, the respective agencies of Hye Kyo and Joong Ki denied any reports about the stars' alleged affair.

While the two may not admit about their secret relationship, they did open up about their ideal mates in their respective interviews. The "Battleship Island" star wants his woman to be cheerful and wise. Joong Ki also admitted that he has never dated a celebrity, but even if he does, he will likely keep it a secret. 

Meanwhile, Hye Kyo revealed in her interview that she is an independent woman and does not think that she would like to get married anytime soon. She added that there is no need for marriage when she is doing what she loves.

The rumored couple's onscreen chemistry is so powerful that the fans find it hard to believe that they do not have a real romance off-screen. In fact, recent survey by PMI, as reported by Yonhap News, says that most fans want the Song-Song duo to date for real, if they aren not dating already.
