On April 20, at the press conference following the end of KBS drama 'Descendants of the Sun', Song Hye Kyo was asked about lead male character Yoo Si Jin. 

A reporters asked, "Would you be able to date Yoo Si Jin if he exists in real life?" 

Song Hye Kyo then answered, "I'd have to think about it... If it happened in reality then I think I would be afraid. He would have to give me trust, and I'd have to think hard for a long time before I decide to date him."

Would you date Yoo Si Jin in real life? Why bother thinking about it for more than a second, right?
